"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

Ground Advantage is dropping ounce tiers for sub-1 lb packages. Today a light item ships in the 1–4 oz or 5–8 oz tier. After July 12, everything under 1 lb is priced at the 15.99 oz rate (~$6.39 commercial base, ~$8.40 retail).
If you set a flat shipping price below that, you eat the difference on every sale. A listing charging $3.99 shipping on a 6 oz item goes from roughly break-even to a ~$2.40 loss per order.
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.

Ground Advantage commercial base, sub-1 lb (approx.)

Before July 12 — 1–4 oz	~$3.49
Before July 12 — 5–8 oz	~$3.99
Before July 12 — 9–12 oz	~$4.99
Before July 12 — 13–15.99 oz	~$5.99
After July 12 — anything < 1 lb	~$6.39
