Several examples in FL - Tijuana Flats, Beef O'Brady's and Cheeburger Cheeburger. I buy from the CC in Ft Myers when I am in that are and use it at a location closer to me. Same with Beef's and TF. When I am near the ones that participate, it's a great time to get a card.
Just make sure it is not store specific. I especially ask at the one where I want to redeem.
