The Blue Cash Everyday Card from American Express is a cash back rewards credit card that offers three different categories for earning potential. Cardholders can earn 3 percent cash back on up to $6,000 in purchases at U.S. supermarkets each year (then 1 percent), as well as 2 percent cash back on unlimited purchases at U.S. gas stations and select U.S. department stores. All other purchases earn 1 percent cash back. This card has a $0 annual fee, and new cardholders can earn a $150 statement credit by spending $1,000 in the first three months of opening the account. For the first 15 months, this card offers a zero percent APR on purchases and balance transfers made within 60 days of opening the account, then a 14.99 to 25.99 percent variable APR.
