It's interesting how easily people mistake orders of magnitude when they are using different units of measure simultanously -- in the article you linked, first they say: give it a mark-up from 0.03p to 95p per half litre; and then: In other words, Dasani is less healthy than regular tap water, but at more than thirty times the price. It's not thirty times the price -- it's three thousand. It reminds me of a Verizon Math story[1]. [1] - http://verizonmath.blogspot.com/ http://verizonmath.blogspot.com/
