Free resources for UK charities: The Freecycle Network

With 9 million members, divided into local sub-communities, the Freecycle Network is the largest consumer-to-consumer marketplace of free items in the world. 
For charities, this is a great forum for sourcing domestic items.
Members can list items they’re seeking or wish to donate. Donors and seekers communicate directly to coordinate pickup and collection. Since this is a consumer network, items on Freecycle range from cat toys to computers. 
Freecycle’s mission is to build a worldwide sharing 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.
Membership is completely free, while the operation is grassroots and 100% not-for-profit.
For further information and details about how to sign up and join the network, please visit the Freecycle website.
