If you have an iPod touch, IPhone, or iPad I highly recommend Viggle. Basically, when you are watching TV you can "check in" a tv show and earn points fromit. I've had the thing less than a week and I just got a $5 Starbucks gift card.
You can aslo watch ads in the app for extra points, or playing trivia games along with the awards shows. For instance, I watched the Grammys for about 20 minutes last night and earned 500 points for checking in, and 2500 for guessing a few awards correctly.
I even checked in a few shows I don't regularly watch - like the ones that come on before or after was I was actually intending to watch.
Anyway, just a suggestion if you wouldn't mind some freebie gift cards for doing something you're going to be doing anyway
