Indeed, just ONE retailer in Sweden have 150+ Switches in stock if I'm reading their inventory right (I could be wrong and they have many more, not 100% sure how to read their inventory listing).

Webhallen probably is the biggest retailer for console games in Sweden nowadays, with their 22 physical shops. (The InfraCity and Web stock is identical, BTW. It's their main stock distribution center.) So it's about 10 units per shop, a balanced stock supply.
And to put this in context: the total of Webhallen's stock nationwide in Sweden would roughly equal one weekly supply to one single Bic store in Japan (where perhaps 10 times as many would queue to get a lottery ticket to buy a Switch).
