Custom Packaging Design Services Near Me: What to Know

If you’ve been searching for custom packaging design services near me, you probably think the hardest part is finding a designer who can make a box look good. Honestly, that’s usually the easy part. The real work is making sure the package protects a product in transit, fits a real production line, keeps freight costs under control, and still tells a brand story in under three seconds on a shelf. In practice, that can mean choosing a 350gsm C1S artboard for a folding carton, a 32 ECT corrugated mailer for direct-to-consumer shipping, or a 1200gsm rigid setup box for a premium launch in Chicago, Atlanta, or Dallas.

I remember one meeting where everyone was so proud of the “premium” unboxing that nobody had checked whether the insert actually held the jar upright. The prototype arrived, we shook it a little, and the product slid around like it was late for a train. Not ideal. I’ve seen brands spend $8,000 on gorgeous artwork and then lose another $12,000 fixing a box that crushed in shipping. I’ve also sat in meetings where a client fell in love with a rigid box prototype, only to discover the magnet closure added 11 cents per unit and pushed the project out of margin. That’s why custom packaging design services near me matter so much: local support can shorten feedback loops, reduce sampling headaches, and keep all the moving parts visible, especially when proof approval takes 12-15 business days and production tooling adds another 5-7 business days.

In packaging, details matter down to the millimeter. A 1.5 mm tuck flap difference, a 350gsm board choice, or a bad barcode placement can be the line between a package that works and one that turns into a warehouse problem. If you’re comparing custom packaging design services near me, you need more than pretty mockups. You need a partner who understands structure, production, compliance, and brand positioning all at once. Preferably someone who won’t send you a “final_final_v7” file and pretend that’s normal (it isn’t). You also want someone who can quote a basic folding carton at around $0.15 per unit for 5,000 pieces, then explain why foil stamping or a PET window pushes the number closer to $0.28 or $0.41.

Custom Packaging Design Services Near Me: What They Really Are

Many brands assume packaging design is mostly about graphics. That’s backwards. In my experience, structure comes first, then material, then print, then finish. A package can have beautiful typography and still fail if the insert doesn’t hold the product or the board score lines crack after a single shipment. I’ve watched a stunning carton go from “luxury” to “why is this flapping open?” in one afternoon. A carton made from 350gsm C1S artboard with a 1.2 mm score allowance behaves very differently from a laminated rigid box built in Dongguan, Shenzhen, or Long Island City.

When people search for custom packaging design services near me, they’re usually looking for a combination of services, not just one person with design software. A proper provider may handle discovery, structural engineering, dielines, visual branding, prototype development, and production coordination. Some also manage printing and fulfillment. Others stop at print-ready artwork and hand you off to a manufacturer. That handoff sounds simple until three emails later nobody knows who changed the barcode. If your provider works with a plant in Ontario, California, or Mississauga, ask whether they can produce a physical sample in 3-5 business days and a corrected prepress file in 24 hours.

Here’s the distinction that trips up a lot of teams:

• Designer: focuses on layout, brand identity, color, typography, and visuals.
• Packaging engineer: focuses on structure, material performance, tolerances, and how the package behaves under load or during shipping.
• Manufacturer: produces the final box, carton, sleeve, or mailer at scale, often in cities like Shenzhen, Ho Chi Minh City, Toronto, or Chicago.

If a provider says they offer custom packaging design services near me, ask which of those roles they actually cover. I’ve walked through supplier negotiations where a brand assumed “design service” included print management, only to learn that every revision required a separate handoff. That adds delay. It also adds risk. It also adds a mild urge to stare at the ceiling for a minute, which I’ve done more than once. On a 10,000-unit run, even a 2-cent change per unit becomes a $200 decision before freight.

“A package isn’t successful because it looks expensive. It’s successful because it protects the product, ships efficiently, and still feels right in the customer’s hands.”

Local support can make a real difference. A same-city or same-region team can review a sample in person, compare substrates under the same light, and catch structural issues before mass production. I once visited a cosmetics line review in which the client had chosen a soft-touch coated carton for a heavy glass jar. On screen, everything looked elegant. In hand, the box flexed at the corners after three open-close cycles. A quick sample adjustment saved them from reordering 20,000 units. That is the practical value of custom packaging design services near me, especially when the supplier is 40 minutes away in Phoenix, Austin, or Newark instead of 40 days away by ocean freight.

And yes, branding matters. But branded packaging only works when it can survive reality. Shelf display, parcel shipping, warehouse stacking, and customer handling are not theory. They’re the test. A package that looks amazing in a render but collapses in a mailer is basically expensive disappointment with a logo on it. Even a premium mailer can fail if the board grade drops from a 44 ECT spec to 32 ECT and the product weighs 1.8 pounds.

How Custom Packaging Design Services Near Me Work

The workflow usually starts with a consultation. A good local provider will ask for product dimensions, weights, fragility concerns, shipping method, target retail price, and the kind of customer experience you want. If they don’t ask those things, I’d be cautious. Good custom packaging design services near me begin with facts, not inspiration boards. Inspiration boards are fine later. First, we need numbers like a 7.25-inch bottle height, a 3.4-ounce fill weight, or a 0.75-inch cap clearance.

From there, the team usually maps the package around the product and the business model. An e-commerce brand needs different engineering than a boutique retail launch. A subscription box needs different logic than a luxury candle. A blister pack has different compliance concerns than a rigid gift box. Packaging design is never one-size-fits-all, and anyone who says otherwise is oversimplifying. Usually by a lot. A brand shipping from Nashville to Denver has very different compression and transit concerns than a store display program in Los Angeles or Miami.

The usual process looks like this:

1. Discovery: define the product, audience, budget, and use case.
2. Measurements and constraints: record exact dimensions, weight, and protective needs.
3. Structural concept: create dielines, inserts, closure methods, and board specs.
4. Visual design: apply branding, messaging, regulatory information, and artwork.
5. Prototype: print or build a sample to test fit and look.
6. Revision: adjust the die, graphics, coatings, or insert geometry.
7. Final approval: release print-ready files and production specs.

For many teams searching custom packaging design services near me, the slowest step is approval, not design. I’ve seen projects pause for 10 business days because three stakeholders could not agree on whether the logo should sit 8 mm or 12 mm above the top edge. That sounds minor. It isn’t. Small changes can affect cut lines, foil placement, and even press registration. Honestly, I’ve watched people debate millimeters with the intensity of a courtroom drama. On a 5,000-piece run, a simple approval delay can push shipping from the third week of June to the first week of July.

Timelines vary by complexity. A straightforward folding carton with existing dielines may move from brief to proof approval in 7-12 business days. A Custom Rigid Setup box with foam insert and specialty finish can take 3-5 weeks before it’s ready for production. Add regulatory checks or complex art approvals, and the timeline stretches further. That’s normal. The goal is not speed alone; it’s accuracy. For a mid-volume order of 5,000 cartons, production often runs 12-15 business days from proof approval, while a specialty magnetic box made in Shanghai or San Jose can take 18-25 business days depending on finishing.

In-person collaboration still has advantages. Press checks can reveal color drift that monitors hide. A matte varnish might feel perfect on a sample, then show fingerprints under retail lighting. I’ve stood on factory floors where one side of a box looked deep navy on the CAD render but printed with a noticeable purple cast because the chosen substrate absorbed ink differently. That’s where local or regionally close custom packaging design services near me pay off. Problems get caught earlier, often before the final offset plates are even mounted in a facility in Portland, New Jersey, or Guangzhou.

For brands building out product packaging across multiple SKUs, starting with one hero item is often smarter than trying to redesign everything at once. That reduces risk and gives the design team a clean benchmark. A single 8-ounce serum carton, for example, can establish the dieline, print tone, and finishing system before you expand to cleanser, toner, and refill packs.

Custom Packaging Design Services Near Me: Key Factors That Shape Your Packaging Design

Before you get distracted by finishes and fancy mockups, start with protection. A $35 serum bottle needs different engineering than a lightweight tea tin. Fragility, weight, temperature sensitivity, and shipping distance all affect the spec. If the package has to survive parcel carriers, corner drop tests matter more than a beautiful lid. Pretty is nice. Surviving a cross-country shipment from Indianapolis to Seattle is nicer. A 16-ounce glass bottle inside a 2-piece carton needs more than visual polish; it needs a fit tolerance that leaves no more than 1.5 mm of lateral movement.

For shipping performance, I always ask: will this package be stacked, dropped, vibrated, compressed, or handled by multiple people before it reaches the consumer? Those aren’t hypothetical questions. They determine whether a corrugated mailer, rigid box, or paperboard carton is the right fit. If your custom packaging design services near me provider skips this, they’re designing for a photo shoot, not the supply chain. In practical terms, a mailer destined for 3PL fulfillment in Atlanta may need a 44 ECT board, while a boutique shelf carton in San Francisco can often work with 350gsm C1S artboard and a glued crash-lock base.

Branding comes next. Shelf impact, color consistency, and unboxing experience influence how customers judge the product before they ever use it. A premium tea brand might want a 1200gsm rigid box with a 157gsm wrapped sheet and foil logo. A value-led direct-to-consumer brand might prefer a 32 ECT corrugated mailer with simple one-color print to protect margin. Both can work. The choice depends on positioning. I’ve seen a $24 candle line sell better in a matte black rigid box in Boston, while a $14 vitamin subscription gained traction in a kraft mailer printed in one ink on a plant-based coating.

Here’s where many brands get confused: branded packaging and package branding are not just decoration. They’re a signal. A matte black box with a blind deboss says something different from a kraft mailer with a single-color stamp. If you’re paying for custom packaging design services near me, the package should reinforce the same promise your product makes. Otherwise you’re asking customers to do mental gymnastics, and nobody has time for that. A customer who pays $48 for a serum expects more than a plain white carton with a sticker on top.

Materials, finishes, and sustainability

Material selection affects cost, durability, and sustainability. Common options include rigid board, corrugated board, SBS or C1S paperboard, molded pulp inserts, PET trays, and compostable mailers. Coatings matter too: aqueous coating, UV spot coating, soft-touch lamination, and aqueous-based varnishes all change both feel and recyclability. A 350gsm C1S artboard carton with aqueous coating can run cleanly on many folder-gluer lines, while a soft-touch laminated box may require slower speeds and a different scuff tolerance.

I’ve had supplier calls where a client wanted a soft-touch, foil-stamped, magnetic rigid box made from recycled content. That can be done, but not without tradeoffs. Specialty finishes can complicate recyclability, and some markets are stricter about recovery than others. If sustainability is part of your brief, ask your provider whether they can document recycled content, FSC certification, or recyclable design recommendations. For background standards and guidance, I often refer teams to the FSC site and to the EPA’s packaging and waste resources at EPA recycling guidance. A supplier in Vancouver, Toronto, or Bristol should be able to tell you whether a paperboard is FSC-certified and whether a local converter can source it within 7-10 business days.

Local providers offering custom packaging design services near me should be able to explain why a 350gsm C1S artboard might be better than a heavier board in a specific case. Heavier is not always safer. Sometimes the right flute profile or insert design gives better protection at lower weight and lower freight cost. I know that sounds unfair, because “more material” feels like “more protection,” but packaging has a habit of ignoring our instincts. A 28-pound carton can cost more to ship than a 19-pound carton even before the price of the board is counted.

What drives price up or down

Pricing is affected by material type, print complexity, custom tooling, order quantity, and finishing details. A simple folding carton with four-color CMYK print and no special finish might be relatively modest. A custom rigid box with foil, embossing, insert, and low-volume production will be much more expensive per unit. With custom packaging design services near me, expect design fees to be separate from sample fees and production costs. A design consultation might start at $250-$750, while a full structure-and-art package can run $1,200-$4,500 before production.

Packaging Option	Typical Use	Relative Unit Cost	Notes
Folding carton	Cosmetics, supplements, small retail goods	$0.18-$0.65 at medium volume	Good for shelf display; needs careful board and print selection
Corrugated mailer	E-commerce shipping, subscription boxes	$0.45-$1.20 at medium volume	Better for protection; print options vary by line
Rigid box	Luxury, gifting, electronics, premium retail	$1.50-$6.00+ depending on finish	High perceived value; more costly to ship and store
Molded pulp insert system	Protective interior support	$0.10-$0.75	Useful for sustainability goals and shock absorption

Those numbers are directional, not universal. Volume, supplier location, freight, and tooling can change them quickly. I’ve seen a project jump 22% in landed cost because the team shifted from a domestic stock size to a fully custom structure that required a new die and longer lead time. That’s the sort of reality custom packaging design services near me should help you model early. A 5,000-piece order produced in Illinois may land at $0.15 per unit for a simple carton, while the same shape in a specialty finish from Mexico City or Shenzhen can climb to $0.31 before freight.

Compliance matters too. Regulated products may need specific label space, ingredient panels, warning statements, batch codes, or barcode placements. A package that looks stunning but fails retail scanner tests is not a success. It is an expensive correction. For retail packaging, your designer should understand barcode quiet zones, legibility, and space for mandatory text. On a 1.5-ounce cream jar carton, leaving 9 mm of uninterrupted quiet zone around the UPC can save a reprint that would otherwise cost $450 in plate and setup fees.

How to Choose the Right Local Packaging Partner

The best way to evaluate custom packaging design services near me is to look at both creativity and practicality. A beautiful portfolio is good, but ask yourself: do these packages actually close properly, ship safely, and print cleanly? I’ve reviewed folders full of impressive mockups that would have failed on a live line because the board structure was too ambitious for the product weight. Fancy is not the same as functional. My opinion? Functional wins every time. If a designer in Philadelphia or Raleigh can show you a sample that survived a 2-foot drop test and still opened cleanly, that tells you far more than a polished PDF.

Ask whether the provider is design-only, manufacturing-only, or full-service. That changes accountability. A design-only studio may give you a strong concept but leave sampling and production to someone else. A manufacturer can produce the box, but may not push branding or structural nuance as hard. The right partner depends on how much of the process you want centralized. A full-service team in Dallas, Montreal, or Los Angeles can often quote the carton, insert, and print in one pass instead of three separate bids.

When I sit with clients looking for custom packaging design services near me, I tell them to compare five things:

• Sample quality: does the prototype match the promise?
• Response time: do they reply in 24-48 hours?
• Revision process: how many rounds are included?
• Production capability: can they handle digital print, offset print, specialty finishes, and inserts?
• Industry experience: have they worked on similar product packaging before?

Look at the details in their samples. Are folds crisp? Is the color registration tight within 0.5 mm? Do inserts fit without forcing the product? Those things tell you more than a marketing deck ever will. If a sample from a plant in Atlanta or Vancouver shows crushed corners after one handle test, that’s a warning sign no branding language can erase.

One meeting still sticks with me. A candle brand wanted a luxury setup box, but the first sample had an insert that pinched the jar lid by 2 mm. The designer loved the render. The warehouse team hated the prototype. We changed the cavity depth and swapped to a slightly thinner insert stock, and the whole package worked. That’s what you want from custom packaging design services near me: the ability to solve real problems, not just present beautiful concepts. The finished package used a 157gsm wrap over a 1200gsm board, and the defect rate dropped to nearly zero on the next 3,000-unit run.

If you’re browsing providers, also ask about minimum order quantities, proofing options, and whether they can support Custom Packaging Products for related needs like inserts, branded mailers, or protective elements. A partner who can connect packaging design to actual product supply often saves time and reduces handoff errors. In some regions, a minimum run might be 1,000 units for digital print and 5,000 units for offset, which affects both cost and timeline.

A practical vetting checklist

Use this checklist before you commit:

• Do they provide dielines and structural specs in editable formats?
• Can they quote both design and production separately?
• What is the sample turnaround, in business days?
• Can they support FSC-certified or recyclable materials?
• Do they understand your channel: retail, e-commerce, or wholesale?
• Can they share case studies with dimensions, materials, and finish details?

That list sounds basic, but basic questions catch the biggest mistakes. Strong custom packaging design services near me providers should answer them quickly and specifically. If they dodge the basics, that’s usually your answer right there. A provider in Houston, Denver, or Toronto should be able to tell you whether their sample shop can turn a dieline around in 48-72 hours.

Step-by-Step Guide to Getting Started

Start with the business goal, not the artwork. Are you launching a new product, refreshing an old one, improving shipping protection, or trying to make retail packaging feel more premium? If you define the objective early, your provider can recommend the right structure and avoid wasted revisions. I’ve seen teams spend two weeks debating foil colors when the box itself needed reinforcement. That kind of detour is expensive and, frankly, a little annoying. A $0.08 upgrade in board spec can outperform a $1.25 finish upgrade if the issue is durability, not visual flair.

Next, measure the product carefully. I mean carefully. Measure width, depth, height, weight, and any protruding elements like caps, pumps, hang tabs, or handles. If the item needs to be removed from the box in a particular way, write that down. A designer can’t guess how your product behaves in use. The more precise your brief, the better your custom packaging design services near me results will be. If the product is 3.2 inches wide and 6.8 inches tall, say so; if the cap adds another 0.4 inch, include that too.

Then create a one-page packaging brief. Include:

1. Product name and SKU count
2. Target customer and price point
3. Brand colors and typography references
4. Material preferences or restrictions
5. Shipping method and storage limits
6. Legal copy, barcode needs, and regulatory text
7. Budget range and target launch date

That brief can save days. Sometimes weeks. A local team providing custom packaging design services near me will usually respond faster when they have enough detail to sketch a structural path without guessing. If you send a 300-word brief and three photos, you may get a ballpark in 48 hours. If you send precise dimensions, target quantities, and a launch date, you may get a production estimate the same day.

After that, ask for concepts or prototypes. Don’t approve purely on a digital render if the package has any structural complexity. Paper behaves differently than a screen. Corrugation flexes differently than rigid board. Even ink density shifts with substrate. I’ve had a 4-color process print look elegant in PDF and slightly dull in real life because the chosen board had more absorbency than expected. That’s normal, and it’s why samples matter. Screens lie. Samples don’t. A physical sample produced in Guangzhou, Nashville, or Los Angeles will reveal whether the black ink shifts warm or cool under daylight.

Test the prototype in the real world. Stack it. Ship it. Open it. Repack it. Put it on a shelf under bright lighting. If possible, run a basic drop test or ask whether the design can be checked against ISTA procedures. For packaging transport performance, the guidance from the ISTA organization is a useful benchmark. Not every project needs full formal testing, but the discipline helps. A quick 30-inch corner drop onto corrugate can expose a weak seam before you spend $4,200 on a full run.

Finally, approve only after checking the production spec. Verify dimensions, artwork bleed, color targets, insert tolerances, closures, and print method. If you’re working with custom packaging design services near me, make sure someone has reviewed the final proof line by line. A 1 mm error can become a 10,000-unit headache. A missing 0.125-inch bleed can cost another proof cycle and delay shipping by a week.

“The best packaging projects I’ve seen were the ones where the brand treated the box like part of the product, not an afterthought.”

That mindset changes the conversation. It shifts packaging from a cost center to a conversion tool, a logistics component, and a brand asset all at once. It also makes budgeting easier, because a package priced at $0.22 per unit can be evaluated against breakage rates, not just appearance.

Common Mistakes to Avoid When Hiring Packaging Designers

The first mistake is choosing based on price alone. Cheap packaging can look expensive for exactly one day: the day the prototype arrives. After that, weak board, poor registration, or sloppy tolerances show up fast. I’ve seen low-cost runs trigger rework that cost more than the original job. If you’re comparing custom packaging design services near me, price should be one factor, not the only factor. A quote that is $600 lower can disappear instantly if the supplier charges $180 for each revision and $95 for rushed proofs.

The second mistake is skipping prototypes. This is especially risky for irregular shapes, fragile products, or packaging with closures, inserts, or magnetic features. A render cannot tell you whether a lid will bow, a bottle will rattle, or a sleeve will snag during assembly. Prototype early. Test often. Even a quick sample from a shop in Charlotte or San Diego can expose a fit issue before the press run.

The third mistake is ignoring logistics. A package might look perfect and still hurt margins if it uses too much cubic space, drives up dimensional weight, or causes warehouse inefficiency. I once reviewed a skincare box that increased pallet footprint by 17% because the shoulder height was redesigned for visual drama. It looked great on a shelf. It was terrible for storage. Strong custom packaging design services near me should factor in fulfillment realities from the start. A box that stacks 20 units per tray instead of 24 units can add real cost across a 12-month forecast.

The fourth mistake is weak communication about deadlines. If your team needs samples for a photo shoot, say so on day one. If a retailer needs artwork approval by a certain date, build backward from that. Too many delays happen because one stakeholder assumes another stakeholder has already approved the dieline. That kind of confusion is avoidable. Also, it somehow always happens on a Friday afternoon. A local partner in Miami or Seattle can only help if they know the ship date is fixed, not “sometime next month.”

The fifth mistake is treating packaging as decoration. Packaging design influences conversion, repeat purchase behavior, and perceived value. A package is often the first physical interaction a customer has with your brand. For branded packaging, that moment matters. A lot. If the box is built from 250gsm stock when the product needs 350gsm, the customer may notice the flimsy feel before they ever see the logo.

From a process standpoint, the best custom packaging design services near me partners will ask uncomfortable questions. How will it ship? How will it be displayed? What happens if a customer drops it? If nobody asks those questions, you’re not getting the full value of the service. A partner in Portland, Minneapolis, or Birmingham should be able to explain why a particular closure, insert, or flute profile was chosen, not just say it “looks premium.”

Expert Tips and Next Steps for Your Packaging Project

If you want faster results, gather the right inputs before your first meeting. Bring product samples, brand files, competitor packaging examples, and any internal requirements in one folder. That saves the first call from turning into a scavenger hunt. For custom packaging design services near me, preparation often shortens the path from concept to prototype by several days. A complete folder can shave 3-4 business days off the back-and-forth alone.

Ask for a milestone timeline. A useful timeline usually includes consultation, structure, first proof, revision one, sample approval, and production release. If someone can’t explain these checkpoints, the project may drift. I prefer timelines with actual business-day ranges, like 5-7 business days for initial concepts and 12-15 business days from proof approval to production release, depending on complexity. For a run of 5,000 units, that kind of specificity matters more than a vague “two weeks-ish” estimate.

Start small if you’re changing your packaging direction. One hero SKU is enough to learn whether the new structure works. A limited run also reduces exposure if the finish, insert, or closure needs adjustment. This approach is especially smart for new Custom Printed Boxes or premium retail packaging concepts. A 1,000-piece pilot in Chicago or Toronto can tell you more than a 50,000-piece assumption ever will.

Request a cost range before you finalize the design. But don’t compare unit cost alone. Compare the full landed picture: shipping, storage, fulfillment labor, damage rates, and expected reorder frequency. A box that costs $0.12 more per unit can still save money if it reduces breakage by 3% or improves pack speed by 15 seconds per order. Those numbers add up fast. On a 20,000-unit year, 15 seconds saved per order can translate into dozens of labor hours and a meaningful drop in packing overtime.

Honestly, I think too many teams search for custom packaging design services near me as though geography is the main filter. It helps, yes. Capability matters more than distance. A good local partner should understand material specs, production realities, and your channel. If they also know how to balance shelf impact with freight cost, that’s even better. A plant in Newark may be close, but the real advantage is whether they can quote a corrugated mailer, a rigid box, and a molded pulp insert without needing three different vendors.

Before you commit, ask yourself three questions:

• Does this provider understand my product and customer?
• Can they translate branding into a package that works in shipping and retail?
• Will they help me avoid expensive surprises?

If the answer is yes, you’re probably looking at a strong fit. If not, keep evaluating. Your packaging affects perception, operations, and revenue. It deserves that level of attention. A supplier who can show a sample turnaround of 72 hours, a proof approval window of 12-15 business days, and a repeat-order price around $0.15 per unit for 5,000 pieces is worth serious consideration.

For teams ready to move, the next steps are simple: measure the product, write a one-page brief, shortlist local providers, request samples, and compare process, pricing, and turnaround before signing anything. That is the cleanest way to evaluate custom packaging design services near me without getting trapped by a pretty mockup and a weak production plan. If your shortlist includes a shop in Atlanta, Houston, or Vancouver, ask for a dieline, a physical prototype, and a landed-cost estimate before you approve the artwork.

And if you’re building a broader packaging program, remember that the best partnerships can extend beyond one box. They can support packaging design, structural development, branded packaging, and the production of Custom Packaging Products that actually fit your business model. That’s the difference between a package that merely exists and one that performs. A well-specified carton, for instance, may use 350gsm C1S artboard with aqueous coating, while a shipping-ready mailer may move to 44 ECT corrugate and still keep the per-unit cost under $1.00 at 5,000 pieces.

If you’ve been searching for custom packaging design services near me, start with fit, not flash. The right partner will help your product look better, ship safer, and sell with more confidence. In many cases, that partner will also be able to manufacture in regions like Guangdong, Ontario, or Ohio depending on your volume, budget, and launch date. Get the sample in hand, test the structure under real conditions, and only then lock the spec. That’s the part people skip, and it’s the part that saves the most money.
