Cheapest alakline water in the valley. Get the prepaid card and pay 50 cents a gallon. You cannot beat that deal. Friendly service.
Edit: the prepaid card does not give you 50 cents a gallon. For 20 dollars they load 2 dollars. So you get free cash. Load 120 get 60 dollars loaded free. Without the card the alkaline water us 75 cents a gallon.
