if I purchase a flat-screen TV will it be installed in my house & instructions given to me, to use it? also, would the old TV be removed? thanks!

Yes, I had excellent service from best buy, I bought a new TV earlier this year, I paid for best buy to install it, they showed me how to use it while at my house. EXCELLENT PRICES and INSTALLATION... Best buy price matches anything you buy. 🌟

I'm sure they do install and deliver or will be able to guide you to the right people that do that I'm sure they'd have no problem removing your TV I'm not sure though if they charge you or not extra for that.
