When you have unwanted items, you can always list them on Craigslist or eBay, but there’s always an element of uncertainty when dealing with absolute strangers. With the Bondsy app, you can list your things so only your friends or friends of friends can see your listings. You can choose to sell or trade your goods for money, a favor, lunch, or anything you like. The app is free in the iTunes App Store, and this iPhone app has been optimized for the iPhone 5.
