When they go outside of the city to buy that sweet, fizzy water you speak of, they discover that other items cost less as well. Anything not food but still necessary in a household that people still need, has a sales tax. When you are no longer paying 8% but 6%, and saving money on a variety of beverages not necessarily sweet, fizzy, water, it really does start to add up. It is worth it. **I don't drink that sweet, fizzy, water. But I, like many of us, have taken that trip across state borders to buy that sort of fermented and alcoholic water, fizzy or not.
