Have you heard of OutGrowingIn? It's a kids and maternity clothing swap. Apparently they will even send you boxes to ship your used clothing in. I haven't used it yet, but it seems like a good deal and I can't seem to find a Goodwill around here. Have you used it yet? If you have, please let us know. I'm at least going to go sign up, and if I end up using it I will let you know!
