Do y'all buy things such as a record player technics and how much who u accept that for

Best Buy is a electronics retail store. They only sell items from manufacturing companies.

I'm not sure they buy those kinds of things at best buy, but an alternative would be selling it on Letgo or OfferUp. Just download either or both apps from the Google play store, take a couple of pics, put a description and list price and hopefully someone will want to buy your items. I've sold numerous things on there. You'd be surprised what people will buy. Good luck to ya.

You need to call Best Buy for that answer.
