Yeah, I remember going into PC World (Ireland/UK retailer, very similar to a smaller best buy) to buy a micro SD for the Nintendo switch. They had the same micro SD card per its ratings and capacity in normal packaging for one price and a more switch matching colour scheme labelled "for Nintendo Switch" for €10 less.

It's hard to tell what's going on:

1. Re-labelling the product to catch the confused parent market?

2. An actually better product for the switch? (maybe better read IOPS that helps loading time?)

3. A worse product but in ways they think you won't notice on a switch? (lower sustained write speed perhaps, basically any SD card can outpace eshop downloads)

All seem equally plausible, but my guess is on 1 or 3.
