BR, I joined Freecycle (it's a yahoo group, but part of a global movement). Whenever someone is getting rid of something they advertise it on there, for free. And if you really want/need something, that's also a place to post an ad.

Most of the unnecessary stuffed toys and other bits and pieces that aren't broken and aren't worth keeping from DD go on Freecycle to someone who is usually all to grateful to give them a home.

It's also where we picked up DD's sandpit, outdoor climbing house, doll house + accessories, some clothes, not to mention the fish tank, furniture for our spare room and the play room. I could go on and on...! I've given away probably about an equal amount of stuff in return!
