To resell items on Roblox, start by ensuring you have a Premium Membership. Only members can resell items. Next, find the item you want to resell from your inventory. This item must be marked as Limited or Limited U.
Once you have your item, go to its details page. Here, you will see the Owned Items section under the price chart. If you own multiple copies, you can set your desired sale price.
Consider checking the average price over the last 180 days to help set a competitive price. After setting your price, you can list your item for sale. Remember, you need two-factor authentication enabled to sell on the Roblox Marketplace.
While reselling requires a Premium Membership, you can still sell other items like game passes, developer products, and plugins without it. These items are more for development purposes and are one-time purchases.
