Because you replied unrelated thing to the post. No one was talking about availability.
I even said that too.
Again, you are missing the point.
but since you want to repeat this narritive.
That is gamestop in my area. Its not available. Only Xss is available so far.
As to why the demand is high,
More people want xbox now, compared to xbox one gen.
Whatever is available now, wont be able to satisfy those users. There are alot of people around the world waiting for both Xbox and Ps5 consoles. They wont get it soon, because Both Sony and MS cant make 50m consoles in 1 year.
