It’s the eBay of unwanted stuff. Instead of toss and buy, Freecycle.
One rule: everything posted must be free. Whether it’s a chair, a fax machine, piano, or an old door to be given away, it can be posted on the network. Or, maybe you’re looking to acquire something yourself? Respond to the posting directly and you just might get it. After that it is up to the giver to set up a pickup time for passing on the treasure.
