Anyone got a Xbox Series S that they can sell it to me?

I need help y'all, I life in Oman and I seriously need a Series S for an upcoming Closed-beta game, problem is the code I got is for Xbox so right now I'm searching for one. My budget is pretty low being 50 rials but I've seen people selling the console used for 60 and below.

I really really need this, does anybody have an Xbox Series S that they aren't using and their willing to sell it.
