All Discover card members can earn 5% cash back through December on up to $300 in purchases a month at all restaurants, department stores and clothing stores and 2% cash back on up to $250 a month in purchases at Amazon.com. In addition, cardholders that link their Discover card to their Amazon account can make purchases using their cash back rewards. There is no annual fee.
Read the fine print: New cardholders qualify for 0% APR for the first six months, then the rate jumps to 11.99% to 19.99%.
