CashbackStacker - Stack portals, cards & coupons to maximize every purchase

Most people use a cashback portal OR their credit card rewards. Almost nobody does both at once - and that's leaving 5-15% on the table every purchase. CashbackStacker shows you the exact combination: which portal is paying the most for your store today, which of your cards to use on top, and any active coupons. Takes 30 seconds. Free, no account needed. Rates update daily.
