http://uk.freecycle.org/ I hope you like it. I think it's brilliant. There are Freecycle groups in everyone's local area. I have passed on quite a few things this way, and also got some good things myself. The last thing I got was a punchbag from a man who'd moved and didn't have room for it anymore. It looked new, and we love it. Anyway no matter how small the things are that people want to pass on, they are always very useful to someone else.
Yes, you could use a charity shop too. But on Freecycle you know that it'll go to someone who wants it. There's a charity shop at the corner of our road, that when they haven't sold stuff that they've had for a while, they fill a skip up. That really annoys me, because I'm sure they could find use for it somewhere. The whole point of Freecycle is to keep stuff out of landfill.
