Houston bros, help me out (IAH airport question)

I'm returning to my country next week, connection in Houston, 5:30 hrs waiting. I want to buy a Xbox series x (if I find one ofc). So this is the question:

There is some VG retail store near IAH ? Is easy to go and back to the airport (transportation)? Do I have enough time to do it? According to Google maps there is a best buy and gamestop store near IAH apparently.

Or the plan is too stupid? Thanks 🙂
