Freecycle.org is another similar option. You will need to request to join the appropriate town or towns to interact with the posts. I think it is less active than facebook groups I have seen, at least in my area, but I have seen a lot of goods move through, so if you don't spend time on facebook, it's a good option. The "wanted" post option allows members to request things which I think is helpful too.
