What are some interesting offers that credit card companies are offering right now?

I have been using a Discover Card for about 5 years now (It was the only one I could get at the time. I had good credit, but I never had a credit card before so this caused my to be in some sort of credit card paradox.) and I know that there are some cards that offer frequent flyer miles and other types of offers. Do you know of any credit card companies that are offering any interesting 'rewards' type programs? BTW, I pay the complete balance of my card every month.|||go to the website and there are tons of option to chose, you can also complare between different cards...good luck
