It's back! Right now, you can get a $100 cash back bonus after signing up for the Discover More Card and spending $500 in the first three months. Plus, you'll get 5% cash back on up to $1500 in purchases at department stores and online shopping through the end of the year. Categories rotate, so come January, you'll be getting 5% back on other categories, like restaurants or gas. The card also offers 0% APR on purchases and balance transfers for 12 months, which means you can a buy big ticket item over the holidays, and pay it back over the next year interest-free. Note that there is a 3% fee applied to balance transfers, but there is no annual fee.
