Discover is offering a 5% cashback bonus on Get More purchases. For this quarter (until Sept 30), the Get More purchases include some big retailers such as Kohls, Staples, Linens and Things and a few more. These give you a 5% cashback reward! For more details and all the fineprint please check their website.

Also if you like to buy stuff from Barnes and Noble online, you get a 7% cashback if you use the Discover card referral link on the Discover card website. The 7% is on top of your regular cashback reward. That's not bad! I am not a big fan of Barnes & Noble but those who like to shop there, may find this a nice deal :-)
