So many ways to earn rewards that go directly to your paypal! If you are a 4sq user, this app works with 4sq to check you in, so instead of just checking in, you check in with points that go towards cash back. Getting paid for checkins you already do is bonus! you can get points by taking pics with certain products for easy points. and if you like downloading new apps, either paid or free, do it from this app to get additional points.
This will definitely make it to my tweets under #freemoney @MercTV
