Free Coke Zero

Chik-Fil-A is at it again with another fun promotion.

Join the "Chicken Wave" online and get a free medium size Coke Zero at a Chik-Fil-A restaurant.

The wave consists of the restaurants fans putting up their photos on the Web site and doing the "wave" that sweeps across stadiums.

In July, Chik-Fil-A gave out free chicken sandwiches to customers dressing like cows. I wonder if they'll go back to it at Halloween?
