I have joined two facebook groups that are online yard sales, and I know there are lots more like them! If you're interested in checking them out they are: Delco's Online Closet Sale and Delaware County Online Yard Sale.
You can post pictures and/or descriptions of items you would like to sell, trade, or just give away.
You can also post items you are looking to purchase!
All buying and selling is done AT YOUR OWN RISK. Be safe. Be Smart.
Happy Selling/Bargain Hunting!
