To sell your stuff on Roblox, start by ensuring you have a Roblox Premium membership. This is necessary for selling items, except for gamepasses, dev products, and VIP Servers.
Next, find the item you want to sell by going to your inventory. The item must be a limited item, which means it can be resold.
Once you have selected the item, tap on it and then tap on the three dots at the top right to access the sales page.
Determine the price you want to sell the item for. It’s a good idea to consider the average price over the last 180 days.
Finally, tap on “Sell” to list the item for sale on the Roblox Marketplace. You can also trade items with other players as another way to make money on Roblox.
