Instead of only posting items or products you intend to sell, buyrfindr.com allows you to post the items and products (and even services) you're LOOKING FOR (called "REQUESTS"), and if your requests match what another user is selling, the site (soon to be an app) matches the two users up, and notifies each of them, and allows them to message each other with details to complete a transaction. Additionally, bf+ includes a localized map of all posts, so users can more easily see what's out there.
