Depends really. People pay for premium water.
That is partially because the water is augmented with stuff like taste, and because it feels more comfortable and hygening drinking it from a bottle. Many elements can be brought in to differentiate it.
Some smucks also thinks its more "healthy" (which can be debated).
If the public had been continously made aware of the reality behind it, they'd probably be less inclined to buy "branded water" and just buy some sweetener or artificial taste for their own water.
That = where the brains of BB's comes in. They think supplement products = differentiated because of smacktalk like "ion filtered" and "anabolic molecular augmentation (not used yet, but meatheads will buy it once its used 
), when it = mostly just the same crap they could have gotten at half the prize some other place.
Even if a product is 2% "more effective" after some obscure technique, those 2% becomes nothing in the grand scheme of things besides becoming a justification for paying a premium price.
Comment: If a cheaper alternative has worse taste and "drinkability" and so on, then it = understandable to pay a higher prize.
