FreeMesa.org is a website dedicated to giving away free stuff! Really! It is a place to exchange free stuff with people in your local community all for free. If you need a new couch, chair, bike, or computer, chances are there is someone in your area trying to give this stuff away for free. FreeMesa makes it easy to bring people together so they can save money, time, and help the environment all by giving stuff away. Likewise, if you have stuff that needs a new home, FreeMesa has you covered!
