Roblox allows players to buy, sell, and create virtual items. Clothes can be bought by anyone, but only players with a premium membership can sell them. Only Roblox administrators can sell accessories, body parts, gear, and packages under the official Roblox user account; virtual hats and accessories can also be published by a select few users with past experience working with the Roblox Corporation. Items with a limited edition status can only be traded between or sold by users with premium membership status.
Robux is the virtual currency in Roblox that allows players to buy various items. Players can obtain Robux by purchasing it with real currency, from a recurring stipend given to members with a premium membership, and from other players by producing and selling virtual content in Roblox.
