The new feature that’s appeared for some Facebook users allows them to sell goods using a new “Sell Something” option when posting to a group.
The new selling option asks the user to share what’s for sale, the price, a description of the item, pictures and pick up/delivery options.
Once you share the post, it formats the details nicely and others can comment with offers or discussion like a normal post would allow.
The new feature appears to be an attempt to bring order to groups made with the purpose of buying and selling goods on the social network.
The feature appears to be in testing right now, with a linked help page.
The page explains that Facebook is not responsible for purchases or sales made on the site .
