I've belonged to our town's Freecycle group for quite a few years now. For those of you who aren't familiar with it, if you have something you want to get rid of (can be absolutely anything), you post what it is and people who are signed up will respond via email if they're interested. Then you just have to decide where to meet to give them the item...around here a lot of folks just go to people's homes to pick up the items. I've seen everything from flowers and fish to baby items and cars posted. Everything is free, you have to give the item(s) away and no trading, either.
So if you're interested, check it out, it's a great way to recycle unused items. Here's the link: http://www.freecycle.org/
