Yesterday I purchased the new RDS GoPlay Game Traveler Pack in a Target store, this is a unique pack because it includes a grip for the whole Switch system that fits in a nice case. What is odd is you won't be able to find any information about this pack, no photos or information on Targets' website or anywhere else online yet.
Some people complain that the system moves in the grip, to stop this minor movement I installed small cushion pads underneath and the grip is solid now!
This info is not about a discount but to inform Switch owners that it exist. It comes really in handy for people with big hands and stops the hands from cramping after long play times with the Nintendo Switch system.
