offers listed on their website. There are some good offers in there. I redeemed a $40 off $200 at Marriott a couple of weeks ago, and just saw a $90 off $300 at Allen Edmunds pop up. All you have to do is click the offer, and then when you spend the qualifying amount it automatically gets deducted from your purchase amount.

It's free money if you use it on stuff you are buying already.
