There is a yahoo based group called freecycle.
This group is world wide same as craigslist.
It's where you can join a local area to give items to others and sometimes ask for them too.
It's popular because it is but a small part of saving our Land Fill.
Simply go to www.freecycle.org post an item that still works and is usable. When you see items from others posted all you have to do is ask the user and go pick it up.
From the main choose an area close to you. Once in the group ask the moderator to direct you a group possibly closer to your home or workplace.
