Today I got a roblox $10 gift card in Kmart for 1k robux premium because I didn't know you know needed $25 because back then you only needed $10. So I bought another $10 through the roblox website, the purchased went through but I got an email saying it didn't work. So now I'm waiting for a refund. I don't know why roblox teamed up with cashstar and when they will fix the problem and not team up with cashstar.
