Assuming you do NOT carry a balance, and any charges over the first $6,000/year the Amex Blue Cash gets you 3% cashback at SuperMarkets, Gas Stations, Drug Stores, and Home Improvement Stores and 1 1/2% cashback on all other purchases.
Note: If you do carry a balance, you will actually get more cashback, but it is offset by the finance charges. I also say any charges over $6,000 because the first $6k per year is a tiered cashback scheme with pretty low cashback amounts. So, this card is great if you charge a lot per year and do not carry a balance. For more details, see:
