Sign up for Wrapp here (you'll need to use your Facebook account) and you will automatically get a free $5 Gap gift card. In order to access your gift card, you'll need to download the Wrapp app to your iPhone or Android smartphone. Once you download the app and sign in, the gift card will appear and you have thirty days to use it. When you are in-store, just ask the cashier to scan it for you at checkout.
You can also give your Facebook friends free gift cards through Wrapp. Just select a friend, and send him/her over a $5 Gap, Sephora, Fab, H&M, SpaFinder, Threadless, Wayfair, Bjorn Borg, Happy Socks, Brooklyn Industries, Wayfair gift card, a $10 gift card at WESC and a $20 gift card at Warby Parker Eyewear. I'm assuming that Wrapp picked up my location and that some of these vendors are local to Colorado. You can also gift a Facebook friends a free month of the Wall Street Journal Digital and Wall Street Journal Weekend. I guess this is Wrapp's way of bringing new users in, as none of the free gift cards can be accessed without downloading the app to your iPhone or Android. Sadly, Wrapp is not yet available in Israel (as I found out when I tried to gift some of my Israeli Facebook friends).
I've been having a blast sending lots of my friends free $5 gift cards (I'm hoping some of them will get a clue and send some back to me!). My favorite are the Gap and Sephora cards. The gift cards expire one-month after they are sent, so use them as soon as you can.
