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 free pair of tropical flip flops. 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.
