Real price drops and working promo codes — every one price-checked against its history, refreshed all day.
Working promo codes on real deals — copy the code, apply it at checkout, and stack the savings on top of the drop.
Every price on Deal Dog is checked before it goes live, then re-checked roughly every four hours, around the clock. If we can't confirm a price, the card shows "See price on Amazon" instead of a stale number, and each card lists exactly when it was last verified. If a deal ever looks off, trust the verified timestamp over the price.
Codes stay hidden until you open a deal. Tap "Reveal Code" and it copies straight to your clipboard as you head to Amazon, so there's nothing to memorize or retype at checkout.
