Scrimpr compares cashback sites and gift card apps. We don't pay the cashback: the site or app does. Cashback site rates are the most you'd get and only pay if your order tracks, so check the site's terms before you buy. Gift card app rates are what you get back when you buy the card. Links marked * can earn us a referral bonus, which never changes the ranking or what you get.

Complete Savings lists 10%, but it's a paid membership you can only join through an offer at another shop's checkout, so it isn't ranked.

Cashback is often excluded on gift cards, marketplace sellers and orders using a voucher code the cashback site doesn't list. Check the site's RS terms before you buy.
