Maybe you saw the funny Superbowl commerical for this. I signed up for Groupon a couple months ago and I am loving it! If you haven't heard of it, once you register, they will email you a special deal, once a day, for local businesses. Sometimes they are even national chains. I recently purchase a Groupon for Redbox. For $1 I received 3 Redbox rental codes or $.33 a movie rental!
I encourage you to click here and try it out. Its free to sign up and you can cancel the email at anytime.
