I found FreeCycle last year, but for the life of me I can't remember where. Probably a friend told me about it.
I have given and received a number of great things on Freecycle, and I can't say enough about it - it's fantastic!! I absolutely love the idea of passing things on rather than throwing them out. I'd rather pass something on than try to sell it and have it sit there for ages. Better that I know someone else is getting good use out of it.
This past weekend I actually got a brand new Ikea loft bed/desk combination for my daughter - I couldn't believe it! But the folks were moving and didn't want to take it apart and move it. Lucky us!
I've given table and chair sets, beds, toys, clothes - all kinds of things away. Plus you meet some really great people.
Definitely join Freecycle - it's so worth your time.
