1. Download Old Navy‘s Snap Appy app for either iPhone or Android.
2. Scan a couple of Old Navy logos on apparel you own or online.
3. Most people report receiving a free pair of flip flops, but there are bigger prizes.
The Flip Flop Freebie shows up as a “surprise” in the app’s “goodie bag” but in order to redeem the “surprise”, you have to bring the gadget with you to an Old Navy store, whip out your gadget, summon the app, and thus reveal the bar code which the Old Navy staffer scans. Then you get the free flip flops.
