I remember seeing a while back a link for a website that some moms have used for purchasing used baby carriers.. It might also have other gear on it.. but it was specifically talking about that.. if anyone knows please share! Thanks!!!
I'm not sure about the link you are talking about, but thebabywearer.com has a For Sale or Trade forum. You have to sign up for the site (create a profile/login), but it is a meca for all things babywearing (and other stuff).
