How DealsFinders verifies Denny's offers
- We read Denny's’ own site first. Offers published by Denny's are checked against the promotions it lists itself. Where an offer is redeemed with a code rather than a link, the button takes you to dennys.com to order and the code goes in at checkout.
- A code found on another coupon site is a lead, not a fact. Those appear only in the community-reported section, clearly marked, and they are never counted as confirmed.
- We never invent an expiry date. If a promotion has a stated end date we publish that date; if it does not, we say so rather than guessing one.
- One code, one offer. When two sources disagree about what a code does, we publish neither claim and look again.
- Expired offers leave the list the day they expire and move to the historical section, so you can still see what a code you have found elsewhere actually was.
- Something wrong? Use the flag on any offer to report it. Reports pull an offer from this page automatically.
