When you sign up for Dairy Queen’s Blizzard Fan Club, you will receive by e-mail a coupon for a FREE 16 oz. Blizzard when you buy a 16 oz. Blizzard!

You will have to enter the location you plan to use the coupon at, but I’m not sure if you have to use it at that location or not. My coupon printed with my name and planned location on it.
