Nothing, but, because I only learned of TFN a week ago and I think the more people who know about it, the better.
The Freecycle Network™ (TFN) is made up of 4,866 groups with 6,854,000 members across the globe. It's a grassroots and entirely nonprofit movement of people who are giving (& getting) stuff for free in their own towns. It's all about reuse and keeping good stuff out of landfills. Each local group is moderated by a local volunteer (them's good people). Membership is free.
Simply find and join your local group, once your membership is confirmed, you simply post 'adverts' in either Wanted or Offered categories. You don't need to give to get, or vice versa.
Give it a try, remember, it's a world-wide network.
"Our mission is to build a worldwide gifting movement that reduces waste, saves precious resources & eases the burden on our landfills while enabling our members to benefit from the strength of a larger community."
