"They're giving away over $2.5 million worth of GAP cards free to viewers at home when you download the app, and they're starting you off with $5 to the GAP when they download the card!
Basically just download the "Gyft" app on your smartphone. Sign in with Facebook or Twitter, and a $5 GAP gift card will show up on your acct. I just did it and it was easy. The Gift card can only be used in-store and expires in Jan.
