In fort worth, Texas (i assume this is national)at local McDonalds, and other restaurants (Popeye's, bennigans, local joints) they have 'front flip' - download the free app and scan the QR like codes ( codes at the register and the tables- scan them before you order to see what you get). Usually I get free ice cream or sundae, can also win free nuggets, etc. Some local places let you win free burgers.
