A:AnswerYes, but make sure to have the best buy app. Some employees wont bother to help you with it. Just go to product scan in the app and it will price match.
A:Answeryes. the controllers are bluetooth. Just google how to sync a new controller to your console and you'll be all set. Chances are you just need to plug the usb into the console, connect the controller and turn both on. That should pair them
A:AnswerYou should be able to, but safest bet is to use the cable that came with the console, if you use any aftermarket cable it could cause damage to the controller because of how it's wired internally.
A:AnswerI don't think they are. I think once they are gone, aftermarket will be the only option. That's what happened with ps3. The playstation website still has some.
