Dasani bottled water comes in bottles and cases. You still get coke rewards points. The water is in a tinted bottle that is bpa-free, and tastes fresher than aqua fina and other brands I have tried. It is convenient, cute, and easy to take with you.
I would rather be drinking American Fare soda, or better yet, coke zero, but if soda is off limits for a while, or forever, you will find it easier to have the bottle in your hand, kind of like people are with fake cigarettes. I really do think their water is better, oh and it is caffeine free.
