TVs are cheap right now like really cheap. I seriously doubt they’re selling them much above cost and making the money back on the advertising and information gathering.
I don’t think any of the TV manufacturers would bulk too much at selling you a TV but it’s going to be at a price of around the lifetime value of your watching habits. You can get a 50-60" reference monitor for about 10 grand. If there was a market for it Best buy would probably sell it.
