How to Get Cheap Shipping Labels
Label costs split into two very different things: the postage, which is where nearly all the money is, and the physical label, which is pennies. Most people optimise the wrong one.
Commercial rates versus counter rates
Carriers publish more than one price for the same movement. The rate at a retail counter is the highest. Rates available through a business account, an online postage platform, or a marketplace integration are lower — often materially so — for the identical service.
This is the single biggest lever for a small shipper, and it is available without volume commitments. Marketplace-integrated postage (the label you buy inside eBay, Etsy, Poshmark, Mercari and similar) is generally priced off a commercial rate card rather than the retail one, which is why sellers who buy postage at the post office counter are usually overpaying for the same parcel.
The practical step is to compare the same parcel, same service, priced three ways: at the counter, through a postage platform, and through whatever marketplace you sell on. The spread is frequently larger than people expect.
Dimensional weight — the charge people don't see coming
Carriers bill on the greater of actual weight and dimensional weight. Dimensional weight is computed from the box's outside measurements divided by a carrier-specific divisor. A large, light parcel is therefore billed as though it were heavy.
This is why a right-sized box saves more than a lighter one. Shipping a small item in a large box with void fill can cost several times what the same item costs in a box that fits it, even though the scale reading barely changes.
Measure the box, not the item, and measure the outside including any bulge. A box that measures a fraction over a dimensional threshold is billed at the higher tier, and reducing one dimension by an inch sometimes drops an entire rate band. If you ship the same product repeatedly, this is worth doing once properly — the saving repeats on every parcel.
The label itself: thermal economics
Direct-thermal labels cost a small amount each and need no ink or toner. A thermal printer is a one-off cost that pays back quickly at even modest volume, because you stop buying cartridges entirely.
Against that, inkjet printing onto adhesive letter sheets carries both the sheet cost and the ink cost, and ink is the expensive half. If you are printing more than a few labels a week on an inkjet, the cartridge spend alone usually exceeds what thermal stock would cost.
Buy thermal labels in fanfold stacks rather than small rolls if you have the storage — per-label pricing drops noticeably at quantity, and thermal stock keeps well as long as it is stored away from heat and direct light.
Discounts and free supplies people miss
Carriers supply free packaging for their own flat-rate and branded services. If your parcel fits one of those formats, the box costs nothing and the rate is fixed regardless of weight within the limit — for dense, heavy items this is frequently the cheapest option available.
Regional and consolidator services undercut the national carriers on some lanes, particularly for lightweight parcels where transit time is not critical. They are worth pricing on routes you use repeatedly.
If you ship consistently, ask for an account rate. The threshold for a negotiated discount is lower than most small businesses assume, and the conversation costs nothing. Bring your actual monthly parcel count and average dimensions — a carrier rep can price against real numbers far more usefully than against an estimate.
Common questions
What is the cheapest way to ship a small parcel?
For lightweight items, the lowest-tier ground or economy service from a national carrier, bought through a postage platform rather than at a counter, is usually cheapest. For dense heavy items in a small box, a flat-rate service often wins because weight stops mattering.
Does the label itself cost anything?
Very little. Thermal labels are pennies each and letter sheets are similar. Effectively all of your shipping cost is postage, which is why rate selection matters far more than label sourcing.
Are free carrier boxes really free?
For the carrier's own flat-rate and branded services, yes — you order them at no cost. They are only usable for those specific services, so they are not a general-purpose box supply.
Is it cheaper to print labels at home?
Yes, once you ship regularly. A thermal printer removes ink costs entirely and pays for itself at modest volume. Below a few parcels a week, printing on plain paper and taping it on costs nothing extra and works fine.

A shipping label maker turns two addresses into a print-ready file. Ours produces a PDF sized for either a 4×6 thermal printer or standard letter paper, with no account and no software install.
How to Create a Shipping Label
Creating a shipping label means producing a document a carrier can read. There are two routes — a carrier account that also sells you postage, or a generator that produces the label alone — and picking the wrong one is the most common mistake.
How to Print a Shipping Label
Most label problems are print problems, not label problems. The file is usually fine; the print dialog quietly rescaled it. Here is what to set, and what to do if you have no printer at all.
Lithium Battery Shipping Labels
Lithium cells are regulated as dangerous goods. Which mark your parcel needs depends on the cell type, the watt-hour rating, and whether the battery ships alone, with equipment, or inside it — and the rules are revised regularly.
