Update On :01 December 2014
Facebook just introduced a new feature that businesses will like.
Facebook announced on Thursday that it is testing a Buy button to help businesses drive sales through the News Feed and on their Facebook Pages.
"With this feature, people on desktop or mobile can click the 'Buy' call-to-action button on ads and Page posts to purchase a product directly from a business, without leaving Facebook," the company said in a statement on its website.
The social network had announced earlier this year that it planned to introduce more call to action options for marketers, including a Shop Now button.
Twitter is also said to be experimenting with a Buy Now button to boost the e-commerce potential from the social network.
Facebook's stock was down by about half a percent on in midday trading.
