I could never understand people paying for water. Now if I was in Mexico etc. yes I would buy bottled water.
I grew up just outside DeFuniak Springs, FL. I still think the tap water there is the best anywhere.
Kirkland store brand bottled water is like $4 for a 40 pack at Costco. You buy it for the convenience, and its a fraction of the price of Dasani.
I never liked water, so I drank iced tea, until yr and a half ago when I tried plain sparkling/seltzer water on ice. Man that stuff is sooo good. I drink 2 liters/day!!! I am very hydrated. I introduced it to hubby, and he loves it too. We load up when on sale.
