If you've been playing Roblox religiously and have amassed a small fortune, you can help out a friend who isn't quite as rich as you are. While there is no way to just give Robux to your friend, you can use the method that other players use to "donate" the virtual currency. Players seeking donations often create clothing -- usually a T-shirt, referred to as a "donation" T-shirt -- to sell to other players in exchange for Robux.
Step 1
Ensure that the player you are donating to has a donation clothing item available for sale. To make and sell clothing, the player must have a paid Builder's Club account. Once the clothing is created, the player must upload it to the catalog and specify the price.
Step 2
Log in to your Roblox account.
Step 3
Click the "Catalog" tab in the blue navigation bar.
Step 4
Enter the name of the donation clothing item in the search bar and click "Search." The name is determined by the creator of the clothing item.
Step 5
Click on the item in the search results.
Step 6
Click the "Buy with R$" button to the right of the item to purchase the item.
