EDIT: Doh! Adam beat me to the punch already!
If you have a pack of Orbit gum lying around, then use the code on it to snag a. They're the perfect footwear for the approaching winter as long as you don't mind frostbite.
Offer expires 12/31 and the fine print actually says you can get three pairs of flip flops per person, per address. There are a lot of six digit codes floating around, such as 074941, but I have a feeling that the more people who use the same code the less likely it'll. Still, can't hurt to try if you don't buy Orbit gum.
