The next time you clean out your house, you might end up selling your old stuff on Facebook instead of Craigslist. According to a report from Techcrunch, Facebook recently did a small test of a "Local Market" feature in its iOS app. Instead of the "messenger" button in the app's bottom navigation bar, a "market" button appeared that took users to a categorized location for buying and selling items. The categories are familiar to anyone who's spent time on Craigslist: you can browse items across cars, furniture, antiques, electronics, clothing, books, and many more. Judging by some posts seen on Twitter, it looks like Facebook has been testing the feature for a a few weeks now.
