"Here's how it works: You list the item you want to trade and some of the things you would accept in return. You provide your item's universal bar code, which is used to post a photograph, a description, and third-party reviews. In an instant, you receive hundreds or thousands of potential matches of your offering and wish list with those of other members. Take your pick and exchange the goods by mail -- or wait for a better deal. You pay for nothing but the postage." (from the book: We are Smarter than Me)
