NEW YORK — More retailers are using such social media venues as Facebook as an entry point into their e-commerce sites, according to the Wall Street Journal, which cited JCPenney and GNC as examples.

Facebook, the report said, creates a new shopping dynamic, enabling consumers to “share” what they’ve bought with friends in real time.

For now, the revenue stream is a trickle, WSJ reported. But expectations are that this potentially could provide a strong flow of revenue in the near future.

Facebook doesn't charge retailers a fee to add the shopping function, WSJ reported, nor does it take a cut of transactions that occur on its site. However, companies typically outsource the project to developers that charge at least $10,000 to add the feature.
