Properly this is an odd a single from Nintendo. The firm is not offering a Splatoon 2 Switch bundle. But they are offering a Splatoon 2 Switch bundle box for $5 in Japan.
This is not some 3rd celebration retail store that manufactured these up, it is Nintendo them selves. They are offering the box for Switch proprietors who by now have a console but want a nicer display box.
It’s out there for buy (Japan only) on Nintendo’s web site here. The box retails for 540 Yen, or about 5 bucks.
I’ll wager 5 bucks that these will clearly show up on eBay in the US marked up five hundred%.
