SALVATION ARMY
The Salvation Army will provide free pick up for most large furniture items. The items you donate are sold to the public and 82% of the proceeds help fund more than 150 adult rehabilitation centers across the United States. Find your local Salvation Army center through the drop-down menu in this link and call or email the local contact provided to schedule a pick up.
