What should I buy the series x or series s

I am thinking of buying hogwarts legacy as a digital game but it is sold out for Xbox one so should I buy the Series X game and put the code in the Xbox one Store?

No. The series X/S version of the game will only work on the Series X or S.

The only way that would work is if it's a code for the digital deluxe version of the game (which comes with both the series x/s and xbox one versions of the game)

Depending on what the game is, if what you bought is for the Series S/X then it will only work on the Series S/X. The One was released before the Series S/X. One games will work on the Series S/X, but not always vice versa.

Many people try to scam others when it comes to new console releases. People are so desperate to buy the new console they don't look at what they are actually buying. For example I seen a PS5 go for $6700 on ebay the other day. That is crazy Also seen
a listing for a xbox series console ( s or x was never stated in the listing) which was the original xbox. Another listing was for a Xbox Series X white edition with a 512gb drive. Obviously this was just the Series S someone was trying to sell as a Series
X

As I have checked, for the Xbox Series X|S version you should see "GTA Online: Megalodon Shark Cash Card (Xbox Series X|S)".

Not the One. I plan on buying a Series S, but wanted to make sure that everything I have on my Series X will be able to be played on the S as well.
