EDIT: Many Fuddruckers are refusing to honor this promotion. I apologize to anybody who tried to use it and was turned down!
Text the word FUDDS (okay, that's not really a word) to 30364 and you'll receive a coupon for a free 1/3 lb. burger at Fuddruckers. Doing this will also sign up you for their mobile alerts, but you can cancel those by later texting STOP. Be sure to call your local joint to see if they're participating, as the coupon says not all are.
I'd like to know the reasoning behind why a place wouldn't participate in a promotion. There should be a test for all would-be franchise owners. (1) Are you going to uphold our brand's image? (2) Are you going to accept all of our darn coupons? Answer both to yes questions and boom, you get a deep fryer and ice cream machine.
What I'm saying is I want an ice cream machine. Fuddruckers, I await your call.
