Bandy is an app that lets people selling items on leading online marketplaces like eBay, Amazon, and Etsy, trade their items with others. In short, Bandy is bringing bartering to websites that have millions upon millions of users. Unlike other bartering apps, Bandy doesn't require users to upload and price individual items. Instead, users link their seller accounts and pull the items they're already selling. The best part is that users can continue selling their items, while they look for great trades. Oh yeah, and it's completely free!
