Freecycle
Business
Participants begin by joining (or creating) a Freecycle list focused on the area where they live. If they have something to give away, they post a message with the subject heading "Offered: Toaster Oven." If they are seeking an item, they post a message with the subject heading "Wanted: Toaster Oven." When members of the list find a match for themselves, it's up to them to take it off-list and arrange for a pick-up; various guidelines are in place to ensure that this is done in a manner suitable to civil society.
There are Freecycle lists online for Canada, Germany, United Kingdom International and all regions of the US.

Note that these are the locations of the groups' headquarters, and not neccesarily where they do their work. A map of areas these groups work in would likely look very different.
