Do you Groupon?

If you haven't heard of Groupon, today is the day to check it out!  Groupon offers you discounted gift certificates for a variety of products and services in your area.  It's similar to restaurants.com, but for more than just restaurants.
 Once you sign up, you will get a email with a daily offering.  Most gift certificates are good for 1 year, so you can snatch up some great deals!
