I have a xbox account and then I got enough points to get 100 robux but the problem is that...

Hi Aryamuang! My name is Stephanie and I'm more than happy to help you out!

Just to clarify, you have successfully purchased the Robux points from the Microsoft Rewards Store, is that correct? To verify, please search for the transaction by signing in to your account using the link below:

If you'd like a copy of the Robux codes to be sent to a different email address, please reach out to Microsoft Rewards Support:

Kind regards,

I used to be able to robux before. This isn't ingame. It's in the app. You cannot use points to purchase on the website.

You can buy robux on PC. On the Microsoft app version. Ive tried resetting etc.

Weridly enough I can buy robux on my other Microsoft account but its not sufficient in credits but I never used it. While when I did buy robux all of the orders went there. Not through my current one.

They receive blocks of codes from Roblox. When that allotment runs out, there are no more until the next batch arrives. No one who isn't directly involved with that transaction knows when that will be, which isn't anyone posting here

They rotate out what's available very now and then. You'd have to wait to see if they add the other option back in.

Hi Aiden, my name is Jhon, and will be a pleasure help you

Currently on the roblox website it says the following:

"Roblox gift cards cannot be redeemed on Xbox at this time"

That said, it is something you should take into account. and later I will tell you some things that you should take into account when buying your robux.

1. To buy Robux to use on Xbox
Make sure you are logged into your Xbox Live-linked Roblox account when purchasing Robux, as it is not possible to transfer Robux between your accounts.

2. For Avatar items, if you don't have enough Robux, the item page will appear with an option to get Robux. Selecting this option will take you to the Robux page, where you can select from the available packages.
For items in experience, if you do not have enough Robux, a message will appear with the lowest amount of Robux that still allows you to purchase the item.

3. You can purchase Robux directly at any time from the Robux screen on the main experience screen.

4. You can buy Robux directly from the Xbox Live website.
