Through the website, anyone can exchange re-usable boxes (cardboard, or otherwise) free of charge. Basically, the site functions like a message board. If you’re looking for a certain type of boxes, have a look around and link up with someone giving theirs away. When you’re finished with your move, just post a message on our boards and give them to someone else. The more boxes you exchange the more resources that are saved, and that’s what going green is all about.
