Kinjo is a free app available for iOS that connects local gamers so you can skip the mall, and deal directly with your neighbors!
You can browse local listings to see what games your neighbors are selling, find a game you want, and request a meet-up at a public location in your neighborhood. When you get the game, just tap to pay with a credit or debit card.
Selling on Kinjo is also super easy. Post a game for sale in less than a minute, then sit back and wait for those meet-up requests to start coming in. Its free to post a game and Kinjo charges a small transaction fee only if your game actually sells.
Why not install Kinjo and see what awesome deals might be waiting for you right now in your neighborhood!
