Thanks for the quick replies. I had figured what you guys are saying is the case, but the lack of information provided on the vizios comparatively was surprising. I too remember when Vizio was a walmart brand. The very first TV I bought in college was a 32" Vizio 720p. At the time it was $400, and I remember thinking that it was specifically a "Walmart" brand or a rebranding of a nicer tv. That being said, the first TV I bought lasted me 6 years until I sold it, and as far as I'm aware the buddy of mine I sold it to still uses it today.
I just started purchasing furniture for my first real apartment of my own, and so in my research I was astonished at the premiums people will pay for "higher-end" TVs. This isn't to say that the picture quality isn't worth the price, but it did shock me when I saw how expensive these nice TVs were. So in that way I totally advocate what Vizio is doing, "stirring the pot" on quality TVs at a more consumer friendly price.
The floor space comment is totally true, there were 3 or 4 sections of TVs, and in each one of those sections a Samsung 4k tv was conveniently placed so a person couldn't help but notice....
I had been under the impression, at least from my recent experience, that Best Buy employees were making commission as well, and it surprises me to hear they don't with as hard as the two guys pushed the more expensive Samsung selections.
