Bartering is based on a simple concept: Two individuals negotiate to determine the relative value of their goods and services and offer them to one another in an even exchange. It is the oldest form of commerce, dating back to at time before hard currency even existed. (Learn more about how bartering evolved, read The History of Money: From Barter To Banknotes.) 

No academics I talked to were aware of any evidence that barter was actually the precursor to money, despite the story’s prevalence in economics textbooks and the public’s consciousness. Some argue that no one ever believed barter was real to begin with—the idea was a crude model used to simplify the context of modern economic systems, not a real theory about past ones.
Nowinska says one of the biggest challenges Swapsity faces is that new barterers think they have nothing to offer. So they offer bad trades. Yet most people have hundreds of skills—from cooking to networking to scrapbooking. The trick is learning to recognize the value of your skills, your knowledge and your talent. Bartering attaches value to things that are not always recognized, or highly valued, in a cash economy—often hobbies that people can’t make a living on but love to do. One Barter Babe trades her homemade canned goods for gifts—mostly other crafted items—she can give away at Christmas. A Swapsity member has traded pounds of fiddleheads she picks at her mom’s house in the country for feng shui sessions.
For instance, each time Apple releases a new version of the iPhone, the second-hand market for older versions of the iPhone enjoys a flurry of activity. However, you do have to be as careful with the barter of used goods as you would be with the purchase of used goods. Be sure everything is in working order and shows no signs of significant damage.
