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.

Nintendo Co. sold 3.5 million-plus units of the Switch 2 in just four days, a record-breaking start for the company’s first new console in eight years.

You can't simply go to the My Nintendo Store and buy the Switch 2. To order the Switch 2, you need to log in with an active, paid Nintendo Switch Online account. Once you do that, you can choose either a Switch 2 standalone console or the Mario Kart World bundle and then hit the confirm button to "register your interest" in ordering a Switch 2.
