And for the third time, Facebook Marketplace is the go to option. However, if you have furniture items too old to sell, call Salvation Army and schedule a pickup. They offer a free service where they'll send someone to your home to pick up your old furniture.
If you have a lot of old furniture that you want to sell, then open an account on Etsy. You can be your own boss and make your own rules. The site is a great way to sell furnishings and other stuff online.
