Poshmark, Mercari, Depop and Vinted issue their own prepaid labels, so you can’t pick USPS services there. Here’s what each one charges for this package, where they publish it.
Poshmark
$6.49
Standard label, up to 5 lb: buyer pays $6.49, you pay $0.00. USPS Ground Advantage, 2–5 days.
One flat USPS Ground Advantage label for up to 5 lb, any distance. Over 5 lb you buy a heavier-weight label: $5 more up to 10 lb, $10 more up to 15 lb.
Who pays: Buyer pays the $6.49 label; you pay any upgrade and any shipping discount you offer.
Mercari
Flat nationwide prices by weight class and carrier (USPS, UPS, FedEx). Packages up to 1 cu ft with no side over 22″ get the cheaper “Best rate”. Mercari changes label prices on October 19, 2026.
Who pays: You choose buyer-paid or seller-paid when you list.
Depop
Depop Shipping (US) uses USPS. You pick a parcel size when you list, and that sets what the buyer pays. Depop shows the price for each size in the listing flow.
Who pays: Buyer pays the price set by the parcel size you pick.
eBay
eBay labels are discounted USPS, UPS and FedEx rates that eBay doesn’t publish as a table. Use calculated shipping so the buyer pays by distance.
Who pays: You set the shipping charge (flat, calculated or free) and buy the label.
Etsy
Etsy Labels are discounted USPS, UPS and FedEx rates bought in your shop; Etsy shows the price when you buy.
Who pays: You set shipping prices (or calculated shipping) and buy the label.
Vinted
Vinted US ships with prepaid USPS labels (a QR code at the post office, or a home pick-up). The rate depends on package size and both locations, and the buyer sees it at checkout.
Who pays: Buyer pays shipping.
How Poshmark shipping works
- Up to 5 lb: buyer pays $6.49, you pay nothing. USPS Ground Advantage, 2–5 days.
- 5.1–10 lb: you pay $5.00 to upgrade the label.
- 10.1–15 lb: you pay $10.00 to upgrade the label.
- Over 15 lb: split the order into more packages with additional labels.
Because the label price is flat, distance doesn’t matter on Poshmark. Weight does: weigh bundles, boots and coats before you accept an offer. For printing, see Poshmark 4×6 labels. For fees, see the Poshmark fee calculator.
How to pay less for shipping
Stay under 1 lb when you can
Ground Advantage costs the same from 4 oz to 15.999 oz at commercial prices, then jumps at 1 lb and every pound after. Shave the extra bag or card that tips a package over.
Use the smallest mailer that closes
Cubic pricing charges by size. A heavy bundle in a snug 10×13 mailer can cost several dollars less than by weight.
Avoid boxes over 1 cubic foot
Past 1,728 in³ USPS bills dimensional weight (L × W × H ÷ 139). A sweater in a big box can bill at 15 lb.
Try a flat rate envelope for dense, heavy items going far
The $11.12 envelope ships any weight anywhere. It beats multi-pound Ground Advantage labels to zones 7–8.
Never buy at the counter
Post Office retail prices are higher than the commercial prices you get online ($7.90 vs $6.93 for the lightest zone 1 Ground Advantage label).
Keep it under 22″ long
Longer parcels pick up a $4.50+ nonstandard fee. Fold coats and long items to stay at or under 22″.
