In order to get a free peppermint milkshake at Chick-fil-A, you'll need to go here and click on “Watch this year's film.” Once the two-minute animated holiday short ends, a red “Make & Send a Gift” button will appear. Click it and you'll be taken to a little game where you can make a milkshake, but there's a “skip” button in the lower right.
Press that button and finally you'll get a form that lets you snail-mail a free milkshake coupon to both a friend and yourself!
