what is flavored water?

No, I don't. I wouldn't buy water at all - since we have excellent water in the tap here in Sweden. Buying water in the store costs about $1 / liter and 1 m2 of water costs $2 at home - there is no chance I would buy the water in the store - especially when it's tap water with some artificial flavor ;-). I do understand that people buy water in places where it's non drinkable from the tap, but in countries like Sweden it's a shame that people do so. Take care and happy lotting!
