"Free shipping" listings (shipping price $0) mean you absorb the postage — the rate increase comes straight out of your margin. They're flagged as Review because the loss depends on what you were paying before.

USPS raises rates 2–3× a year, and each one quietly turns profitable listings into losers. I'm building a free alert service that re-checks your listings before every rate change and emails you the ones that need a price bump. Drop your email for the beta.

What's changing on July 12, 2026
USPS is eliminating the cheap 4 oz and 8 oz tiers on Ground Advantage Commercial. Today a light item can ship in the 4 oz ($5.50) or 8 oz ($6.03) tier at Zone 1. After July 12, everything under 1 lb is billed at the 12–15.99 oz rate (~$6.16 commercial at Zone 1, more for distant zones; ~$7.90+ retail) — the cheaper sub-12 oz prices are gone. It's part of an ~11.8% average Ground Advantage Commercial increase.
If your flat shipping charge is below what USPS now costs, you eat the difference on every sale. A listing charging $4.99 shipping on a sub-1 lb item pays ~$6.16 to ship at Zone 1 — a ~$1.17 loss per order, and more to farther zones. The July 12 tier cut is what pushes the lightest 4 oz / 8 oz packages up into this floor.
Free-shipping listings are hit too — the postage you absorb just went up, straight off your margin.
Items 1 lb and over are largely unaffected by this specific change (their tiers stay). If your CSV has a weight column, map it and we'll skip those.
Buying labels through eBay, Pirate Ship, or a 3PL? The tier change is to USPS's published commercial price list. USPS says accounts with separately negotiated commercial rates aren't automatically affected — but most marketplace/platform rate cards track the published structure closely, so check your provider's July rate card. This tool screens against the published commercial floor.
Zone 1 (local) commercial rates shown; distant zones cost more. On July 12 the 4 oz and 8 oz tiers are eliminated, so every sub-1 lb package is billed at least its zone's 12 oz rate — which runs $6.16 (Zone 1) to $7.13 (Zone 8) (set your zone in step 2 above). Packages that genuinely weigh 12–16 oz pay the 15.99 oz tier, up to ~$8.40 at Zone 8.
