Good news for fans of online shopping! No, this is not a mangosteen peel ya. But Facebook will soon release an online shopping feature on its website. Facebook is trying out the "Buy" or "Buy" that appeared in those posts originating from the online store page or e-commerce. This button can be accessed through desktop and mobile devices. Previously, as is known, the online store page on Facebook, option that appears is "Like" if users like post-its, or the "Comment" to comment. Buy button will direct the user to connect up to the purchase of goods. This method is more efficient than the need to go first to the site or e-commerce page.
