Facebook will expand its buying-and-selling Marketplace service to 17 countries in Europe.
Launched almost a year ago, Marketplace makes it possible for Facebook users to search for stuff, mostly second-hand goods, that people are selling nearby.
Facebook's buy-sell groups draw about 550 million people each month.
In May, 18 million goods were put up for sale in the U.S. There are no figures, how many of items were sold, because most of the transactions are paid in cash and offline.
