Additionally, Discover cardmembers can now earn double cash rewards on their purchases made at Amazon.com through the end of 2011.

Starting today, Discover cardmembers can pay for their Amazon.com purchases using Cashback Bonus when they link their Discover card to their Amazon.com account. Cardmembers can apply as much or as little of their Cashback Bonus as they want toward their Amazon.com purchase, with no required minimum, and have any remaining balance charged to their Discover card. Using Cashback Bonus to pay on Amazon.com is simple and straightforward, since a dollar in Cashback Bonus equals a dollar on Amazon.com. This gives Discover cardmembers another way to get clear value from their Cashback Bonus from Discover.

Discover cardmembers also can automatically earn Double (2%) Cashback Bonus on up to $250 in purchases each month on Amazon.com through the end of 2011. Cardmembers do not need to sign up: they simply need to use their Discover cards to start earning extra rewards. Discover cardmembers who have a Miles by Discover or Escape card will earn Double Miles.

"Providing more Cashback Bonus opportunities for cardmembers with Amazon.com is a natural fit for Discover. We know Amazon.com is just as committed to providing customers with value, convenience and service as we are," said Dana Traci, vice president of rewards at Discover. "We also know Discover cardmembers love their Cashback Bonus and have earned more than $650 million of it this year alone. These new features will not only help them earn more of it, but also allow them to use rewards to get millions of items at Amazon.com, when they want them, without having to leave the site."

"We are excited to offer Cashback Bonus as a new way for customers to shop at Amazon.com through our Shop with Points program," said Matt Swann, vice president of payments at Amazon. "Amazon's broad selection of products combined with the convenience of using Discover's Cashback Bonus directly at Amazon.com provides our customers with an even better shopping experience."
