What a great little idea! Find your local Freecycle Community and use it to "find homes for stuff too good for the land fill". The rule is that it's got to be for free. If you want to sell, use ebay, a local paper or go to a car boot sale. If you can't sell it, give it away. If you can't give it away, recycle it. Free your inner packrat!
Locally, I've discovered a pretty active East Berkshire Freecycle Group.
