Yeah, it's hard to find a Series X, indeed. But I've seen availabilities of the Series S in several european countries, even in supermarkets (next to the One S, with a similar package and sold at the same price, very confusing)

Says "No disponible." for me.

Well, that's a pretty odd way to discover I live in a parallel universe, but let's stay positive !

Weird indeed, I couldnt find that specific listing when I seached Amazon Spain myself, but found this one:
https://www.amazon.es/Microsoft-Xbox-Series-S/dp/B08JDTCXRG/ref=sr_1_2?__mk_es_ES=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=xbox+series+s&qid=1616081845&sr=8-2

For me this one says "Disponible a través de estos vendedores." Which I guess means available from other sellers.

Scalpers trying to sell the console at a higher price due to the lack of stock.

Interesting that nearly 1/3 of PS5's sold in Spain are the digital version. It doesn't sell anywhere near that proportion in Japan. I'm not sure if that is an indication of popular the digital model is in Spain or how limited the supply is for the disc model of PS5. Maybe a bit of both?

Why would Amazon do that ? That's weird, on my side it's sold by Amazon itself and eligible to prime delivery.

But anyway

I’m seeing “en stock”, you just have to change the zip code to a one from Spain.

I checked and it says "item non disponible" or item not available

I know people don’t want to accept the true sometimes, but if you change the zip code to 28015 (Madrid), Xbox Series S clearly appears as “En Stock” (In stock)
