meh i cant find the exact same tv i was looking for, where it was blatantly the EXACT SAME MODEL NUMBER, but different specs.
but like WT said, its usually pretty obvious, like there will be four models of the same type of tv, and walmart will have the lowest tier model. but basically, if youre about to buy a TV from walmart, and you try to research it but nobody else out there sells it, walmart only, then yea, somethings up. they definitely subcontracted the name brand manufacturers to make cheaper versions with less quality material in that instance
i cant hate on them all the way though, if youre looking for a value tv, key word value, and its the exact same model with the same specs and part and all that, it makes sense to buy it cheaper from walmart / kmart / target. generally though when speaking on high end LED/LCD's and high end plasmas, walmart is not the way to go
