    It looks like Facebook is trying to get in on the e-commerce game. The social network is now testing a "buy" button on its website to facilitate purchases by consumers for items advertised on the site. Facebook says it will be available on mobile and desktop versions, and will start out with a "few small and medium-sized businesses." Facebook will not take any portion of the revenue for now, and credit card transactions will be handled by a third-party.
