Roblox is releasing Roblox Wallet, a new way for developers to instantly receive money and transfer it to their bank. Additionally, you can also buy Robux at a discounted rate.
You can also get a physical Roblox Card to make purchases anywhere you go.
@Cmdr_OlIVer turns out I won't be able to do it for robux lol, roblox is having a problem rn where they're incorrectly flagging people paying for commissions as "third party purchases" and banning them 😭😭😭
