Is it safe to buy in box stuff from a local ad.

I found an ad on a local website where this guy is offering units at a little above cost. He was in the busniess for years and still has a connection to wholesale prices.

You will get NO WARRANTY from the manufacturer, and it will cost you the same (or more)after paying a licensed pro to install it as buying from the pro in the first place.

Is installation included?

BTW, how do you know cost?
