I am going to have it my way and go to Burger King and buy one Whopper and get one Whopper free. That is the way I like it. I love getting something FREE! Burger King is offering a Buy One Whopper and Get One Free December 9, 10 and 11 (at participation restaurants). Take a friend or co-worker out to lunch today for Whoppers. They will be so surprised you asked and you will save money buying their lunch.
