When did u sell it? X1X was available readily in stock and demand was there for X1X.
Series Consoles demand plummeted after MS went 3rd party. So dont expect much.
Few retailers are still selling it

But yeah big retailers only got Series S now.
MS slowly slowly reducing production of Xbox worldwide.
No he not getting 30k for Series X here. No way.
