GameStop

Yes. Super Smash Bros Ultimate for Nintendo Switch has been out since December 12 of last week .

No, but Blue Ox in Greenville does

No they don't do that sort of thing. You would have to send it to Nintendo or try and fix it yourself. Best option, in my opinion, would be to sell it on eBay with the issue listed out then purchase a used one on eBay. Bit of a hassle but cheaper than dealing with Nintendo, probably.

That depends on what type of game console u have if u have regular xbox or xbox 360 or better u can connect the controllers to the system either by pluggin them to the charger cord after u put batter pack on the controller or u can do it by another way..on the top of the controller were the charger plugs in at rite beside that is a little circle that u can push to reconnect theres also one on system by the pull out tray push the two buttons togather and it should connect...now if U already had it connected n it looses connection to system it could b the battery pack needs to b replaced. Im having a little trouble with this part myself

Yes, GameStop offers codes. I recommend buying them online from www.gamestop.com
