Many points programs can be redeemed on amazon. Some offer less than .01 per point but chase UR and discover cashback is .01 per point. You could also just get cashback at that rate and buy what you want at store of your choice.
Or you can get GC for your points. Chase UR and citi TY are .01 a point while Discover gives you better value for redeeming for GC, generally a $25 GC will cost $20 of your cashback.
You may also want to consider getting a cashback credit card like citi double cash or fidelity amex, both of which pay .02 for every dollar spent.
