Facebook launched its Marketplace in 2007, giving users the ability to sell household goods via the social network. Now, Marketplace has been given an overhaul, which has been developed by classifieds vendor Oodle.
If you're currently using Marketplace, you'll have the option to transfer your item(s) to the updated version.
If you want to access Marketplace, search for it in the Application Directory.
With the update comes a charitable effort. A new feature called "Sell for a Cause" allows sellers to donate profits to charity.
