Do you guys do trade in’s i was wondering if i could trade in my PlayStation 4 for the PlayStation 5 a few days before it drops

Ho I never trade in I believe best buy takes trade in for Playstation You can contact Best Buy awesome 👌 customer service 👏 Hope this helps 😀

Yes

Is there a difference in plug and play and car play

You probably would be able but you may still need to bring cash of your payment. Because a PS4 is no where close to the price of the PS5.
