Local means near you.

KeystoneXchange is founded in Pennsylvania, but you do not need to live there to join. Choose your area to find items nearby, or explore listings across the marketplace.

Free to post. No commission.

Add photos of your item, an honest description, and your asking price. After review and approval, buyers can discover your listing and message you.

Work out the exchange together.

Ask questions, agree on the details, and arrange a suitable pickup. Buyers and sellers handle payment directly.

A place for every community.

People in every state can join from day one. Available listings depend on what members in each area have posted; new communities may have fewer listings at first.
