Codes that don't work
Bigger codes, tested at checkout.
Search results and AI answers keep promising 25%, 30%, 40% off. Most of those codes expired long ago. We apply them at each firm's own checkout from a US connection and record what the checkout actually says.

Seen a code that doesn’t work?
Send it to us. We apply it at the firm’s checkout and, if it fails, add it here with the checkout’s own message. Found one that works and beats ours? We want that too.
Why fake codes rank so well
Coupon sites publish every code they’ve ever seen and rarely remove the dead ones. AI answers then summarize those pages, so a code that expired a year ago can still be the first thing you see. A bigger number gets more clicks, which keeps it near the top.
We only list a code as working after we’ve applied it at checkout ourselves, and we put the date next to it. How we test is on How we check.
