Freecycle.org
Have you seen it? It's an organization that "recycles" by connecting people who need and those who want to get rid of stuff. It's organized into local groups so you can only see what's available in that group once you've joined. The things have to be free--no strings attached. It's a very fun way to clean out what you don't need and maybe get what you do.

We just got 2 grown-up bikes (admittedly that need some work--but they were free and appear at this point to only need some minor work) through this. How cool is that?!
