Nintendo Switch Trade-In value $20

I just bought an Asus Ally from Best Buy and have been keeping tabs on the Black Friday Sales in case the sale price ended up being lower than what I paid, I was told by staff I could be reimbursed the difference if the sale price was lower.

Anyway.

Got curious about trade in prices and a Nintendo Switch has a trade in value of $20. I thought gamestop was bad but I think they offer up to like, $60. Crazy.
