Sign up for “Joe's Mail” and you will receive a coupon for a FREE appetizer in your e-mail in-box within minutes. They say they will send periodic specials. I just did it and they ask for your birthday, which usually means you will get something free for you birthday. Coupon expires 14 days from the time you sign up so plan accordingly. Find a Joe's Crab Shack here.
