i only buy bottled water when i am doing long drives or as part of my meal allowance at work because im not drinking sugary/carbonated drinks anymore.
I never bought dasani, i tried it once when my parents got me it and it was fucking disgusting so i never had it again....and it was pulled from the shelves when it was published.
If you want fresh drinking water that doesn't come out of the public water system, get an atmospheric water generator. It squeezes the water vapor out of the air and puts out a few gallons of water a day.
