Credit card deals from Discover come in the form of higher rebates for holiday shoppers.

Discover card customers who do their holiday shopping at Amazon.com will receive 2 percent cash back on up to $250 in purchases each billing period through 2011. Card customers that link their Discover card to their Amazon.com account can pay for purchases using their Discover cash-back rewards.

"One dollar of cash-back bonus is $1 to spend at Amazon.com," says Dana Traci, vice president of rewards and product manager at Discover. "There's no minimum and there's no maximum."

Through the end of the year, Discover is offering a 5 percent cash-back bonus on up to $300 in purchases at restaurants, department stores and clothing stores on the Discover More card. Customers can enroll for this promotion through the Discover website.

Additional cash-back rewards are available to Discover card customers who shop online through ShopDiscover, an online shopping mall with more than 200 retailers. Throughout the year, Discover customers earn a 5 percent to 20 percent cash-back bonus on purchases made through ShopDiscover. Starting Nov. 13, more than 70 retailers will increase the cash-back bonus amount they offer by 5 percent. Partners such as Best Buy, Target and Barnes and Noble will be offering 10 percent cash back for a limited time.
