Roblox Premium is a subscription-based service that gives players access to special economy features that aren’t available to regular, free players. These economic features include access to the Marketplace where you can buy, sell, and trade items. Premium members receive a monthly Robux stipend and get a bonus 10% to any Robux they purchase directly from the store. If you’re a Roblox Game developer, you also get bigger Robux payouts from sales in your games with Builders Club membership.
