:o If you can drink water from your own taps at home, why buy the same water just because it's in bottles? I wouldn't.

Sidenote: I've been to alot of countries where you can't drink tap water and I always ended up longing for the day to get back to Sweden where you can drink water right off the tap 'cause it's so clean and most importantly because it's so good and you don't have to buy it in bottles to have a 'delicious' glass of water :3
Though the last time I was at the southern part of Stockholm's archipelago (Landsort), the water tasted funny 'cause it's brackish (mix of seawater and fresh water) from the Baltic Sea (drinkable!).
