Reporting a dead code
Include the store page and what the merchant's site showed when the code failed (a screenshot helps). Confirmed-dead codes are marked expired the same day — that promise is part of how verification works here.
Merchants
If you run a referral program listed here and want terms corrected, use the same address — corrections to factual claims ship immediately. Note that placement on this site is not for sale; see the disclosure page.
