In North America you can now only get digital versions of games. The store will stop selling physical products due to the corona virus.
On the US site of the Nintendo store is a disclaimer explaining that there are currently no physical games for sale: “Due to coronavirus precautions and on the advice of federal and local guidelines, our processing centers are closed and we cannot receive orders for physical products until further notice. Digital products are still available. We apologize for the inconvenience”.
Currently, this measure only applies to the US Nintendo store. There are still physical products for sale at the European store.
