3. Freecycle
Freecycle is the official website for The Freecycle Network, a nonprofit organization with the mission of keeping potentially useful items out of landfills. The Freecycle Network is spread across more than 110 countries and has millions of members.
The site has helped keep thousands of tons out of landfills by offering free goods to people who can put them to good use. To use the website, you need to sign up to become a free member and join your local Freecycle groups.
Now, you can browse the free items others are offering. You can also see the items people are looking to receive, and respond to the individual posts to arrange a pickup. Everything listed on the site is legal, free, and appropriate for all ages.
