A:AnswerClick Menu on the Best Buy website scroll down to support and services, scroll to the very bottom where it says trade in your device and from there you should be able to get an estimate of what your old switch is worth. I'm not sure if they stopped taking trade-in post pandemic but it's worth a try.
A:AnswerWhen you preorder the product that basically means that you reserved a spot to pick it up, you should get a notification that your order should be ready to be picked up

A:AnswerUnfortunately, the only way youd be able to get just the joycons is if someone were to trade in just the joycans without the console. Because they are part of the console bundle, the joycons are not currently sold separately, and likely, only would be sold as such, used. So you wouldnt be able to get them new without the whole console.
