P.S. Yes, it does work with the Nintendo Switch. It is $1.00 cheaper than the Nintendo branded memory card being sold on Best Buy. Add some cash back offers to this and you can get a great deal on a great card.
P.S.S. I bought this for $18.99 (see attached). It maybe a case of YMMV. Worse case, you maybe able to get a price match.
