Anyone know where can you get restaurant discounts or coupons?

One thing that I like to do is go to the website for the restaurants you like and sign up for their e-newsletter. Most sites will periodically send out coupons for a free appetizer or a few dollars off your total purchase. A lot of them also have some sort of birthday club, ranging from a free dessert to a free meal. You have to deal with a few random update emails, but it's worth it for the free food here and there.
