As long as you can get the cart version too, that's good for them. However, I was thinking they should let you buy each of the variety pack item separately with seperate download codes included.
And they are missing a golden opportunity to have them come, not with a boring code, but with a 3-d raised (or more cheaply, cut-out) cardboard QR-type insert. This would (1.) be faster than typing in a code (2.) work without the switch having a normal camera (3.) be aesthetically consistent & cute (4.) actually be of possible use to confused switch owning parents that somehow don't have completely working joy-cons. And yes, there are many of reasons I can list why they might not. Needing to use the IR camera first thing would show them where it is and make sure it's working.
