I just joined this site. Folks post items that they don't need or request items that they want. If you're the first to respond to an item that is posted you can get it for free. It's a good way to get rid of stuff and to get stuff. I've been able to get a glider rocking chair and a futon bunkbed.
Here's the link if anyone's interested: http://www.freecycle.org/
It's also a great way to meet nice folks. Hubby and I met a really sweet couple who live really close to us and they have kids the same age as our kids and on top of that also have a pair of autistic twins. We're planning to keep in touch.
