the website is
www.freecycle.org
There are groups in Canada too. I love our local freecycle. I have given away a lot of things like clothes, books, misc. and I have recieved a whole bag of clothing for my son another whole bag of clothing for my daughter and 50 books. With the books I took about a doz or so for me and took the rest to school and shared them with the rest of the staff they were gone in about an hour .
Check it out it is really worth it.
