With over three million items, SwapThing helps users swap with folks across town or across the country. This year, the company encourages consumers to go holiday swapping instead of shopping. Through the company's matchmaking technology and user-created communities, it has connected over 18,000 p2p swaps. SwapThing charges $1 per transaction. Check out the video for more about SwapThing from Jessica Hardwick, who talks about why she started SwapThing based on her own swapping experience when her cat was sick. She swapped with a veterinarian, who cared for her cat while Jessica provided accounting services.
