The part nobody does
Ever bought something, and two days later it dropped?
It happens constantly: Amazon prices change several times a day. Most stores, if the price falls while you're still within the return window, let you claim back the difference — but nobody tells you, and you're certainly not re-checking something you already bought every day.
RateRadar does. After you tell it "bought", it keeps watching that price for the whole return window. If it drops, it pings you with how much you can claim and what to do. It's like having someone check the receipts for you.
Return and refund rules vary by store and product: RateRadar flags the opportunity, you make the request in a few taps.
