This is a very interesting site I just recently found out about. I'm not sure if this is something most everyone else has heard of before, but in case you're like me and haven't heard of Zwaggle before, here's the scoop!
Zwaggle is basically a community of parents that exchange kid and baby items from clothes to toys. It is very cool in that no money is used, just "points." Parents join (for free), list "gently" used items and earn points. Then those points can be used to "purchase" other items listed on Zwaggle.
So if you haven't checked out Zwaggle.com before, you should go take a look around!
