This is an error in MS website, but here is the thing. And it works so far.
- Go to MS store
- Purchase Diablo 4 standar edition
- Wait and open the store again in a couple of minutes
- See the price of Ultimate Edition
- It shows $44.90. Purchase it.
- The Edition includes the standard edition
- Cancel the Standard edition
Sorry that I am on the bus so not sure whether you understand the process. But IT Works!!@
Absolute deadset legend OP! Working perfectly
