Facebook’s Marketplace may soon expand outside of peer-to-peer sales. Today, Marketplace has begun showing a new Daily Deals tab on the mobile app for select users, sourcing deals from eBay. The new partnership allows users to browse eBay deals inside the Facebook app, but they must go to eBay’s site to check out. The Daily Deals feature is rolling out to select users for now.

“We're conducting a test to determine if people are interested in shopping for discounted products when they visit Marketplace,” a Facebook representative told The Verge. As with all Facebook tests, the feature may not end up being offered to all users, or it may be killed if users don’t love it.

Facebook Marketplace, which relaunched last fall, gives people a way to buy and sell on Facebook’s platform, marking the company’s deeper involvement with e-commerce. It’s been considered a competitor to Craigslist and eBay, which makes this new partnership a bit unexpected.

This week, Facebook expanded the Marketplace feature to 17 European countries, which include Germany, France, Spain, Italy, Ireland, Portugal, the Netherlands, Norway, Sweden, the Czech Republic, Austria, Belgium, Finland, Denmark, Hungary, Luxembourg, and Switzerland.
