At over 3.5 million units sold in just four days, the Nintendo Switch 2 is now the fastest-selling game console of all time, and shows no signs of stopping, with some retailers still having trouble keeping them in stock.

Best Buy began selling the Switch 2 at its retail locations on June 5. It previously said it wouldn't sell the handheld at its online store during launch week, but it made additional consoles available on June 11 around 12PM ET. That restock lasted for the better part of an hour and required in-store pickup, but the device is now sold out again.
