What a great concept! You sign up as a free member and then join a group in your area. You can list things you want or things you want to get rid of. Then someone who is interested contacts you and you just give it to them...free OR you get what you want...FREE! This is a great way to recycle and re-use those items you no longer want, need or are just tired of and someone else gets the joy of having it.
I love the concept but just a little word on your privacy and security. It would probably be wise not to give out your address or personal information and meet some place away from your home. Most people I believe are honest but it's always wise to be on the safe side.
