Sorry if this is not the right forum to post, but I was ordering the Xbox One S Minecraft special edition at microsoftstore.com [microsoft.com]
, and on the checkout page, i was provided with the option to use Microsoft account balance to pay for it.
It says it will charge immediately if you use such balance.
All those Xbox credits just became a lot more valuable, considering we can get them at 10%~20% off and from Bing rewards.
Edit: just preorderd a Xbox One X using Xbox credits.
Edit2: Split payments is also supported. Thanks SlickdealMasterFlex!
