[Mercari](https://resellerindex.com/changes/mercari/) Postage Effective May 7, 2026 · announced Apr 7, 2026 From May 7, 2026, Mercari's prepaid USPS Ground Advantage and Priority Mail labels reflect USPS's temporary 8% price increase of April 26, which USPS called a transportation-related price change and Mercari tied to rising fuel costs. Mercari's Media Mail and First-Class Envelope labels were not affected. USPS's temporary prices run until 12 a.m. CT on Jan. 17, 2027. Mercari prices its labels the same in all 50 states rather than by zone, so where the buyer lived didn't matter. Its rate table "updated May 7, 2026" listed 1 lb Ground Advantage at $7.48 at the Best rate and $7.59 at the Standard rate. Mercari's next change to its Ground Advantage and Priority Mail label prices, announced September 17, took effect on October 19. Where the seller paid shipping, the higher label price came out of the sale. Your net on a $10 / $25 / $50 sale: n/a / n/a / n/a Mercari didn't publish the label prices before and after May 7 side by side, so the change per label can't be calculated from its pages. On USPS's own prices the 8% added $0.70 to a 1 lb retail Ground Advantage label in Zone 1.

Before an update goes live, scripts check every page against our data files for the key postage prices, platform fees and dates we track, and check quotes on our USPS pages and most fee and reference pages against saved copies of their sources (our tax and law pages aren't covered yet). A full-time reseller owns and runs the site. No page is marked as read and checked by the owner yet; when one is, it will say so, with the date. Our pages link the official sources they use, or the pages that do, and show when we checked them. Spot an error?
