I'll never buy another TV unless it's from Costco. Besides being cheaper and having a better return policy, the display models aren't set to demo mode, so you can see what the TV actually looks like with regular settings. Plus the customer service in general from the workers is much better than what you'd get at a Best Buy or Wal-Mart.
Generally speaking, Costco is the right way to shop for the kinds of stuff they offer- roll into an unfurnished warehouse, pile up whatever you want or can afford directly off the pallet, and get the hell out. I don't need a "shopping experience" or a bunch of advertising/up-selling when I'm just buying everyday stuff (preferably store-brand/generic) in the cheapest bulk packaging available- I just need CREAM SUBSTITUTE, DRY, NON-DAIRY, 5 KILOGRAMS or my BEVERAGE BASE POWDER, ORANGE, SUGAR-FREE, 5 KILOGRAMS NET WEIGHT and 48 BATTERIES, AA, ALKALINE, 2500MAH, M306 and so forth.
I got more styles than prison got bricks- ain't that some shit?
