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.

It’s just been a few days since the Nintendo Switch 2 launched, and most places have already sold out. There were restocks here and there throughout the week, but as of last weekend, consoles have been snapped up almost everywhere.
