The only reason I buy it is so that I can have it where I work. Otherwise at home my refrigerator has a cold water filtered facet that is quite cheep to operate. The bottled water that I buy costs about $0.12/20-oz bottle, or about $0.75/gallon. If you are paying much more than that I'd suggest you start buying a different brand of bottled water.
The best tap water I ever tasted in my life was around the Great Lakes in New York State (not far from American/Canadian border). I went there on a business trip once, stopped at a restaurant and couldn't stop myself drinking lots of water. I have not tasted anything like it since then either.
I like sparkling water - I used to go through almost a case of Talking Rain per week. Seattle has really good water so I went out and bought a 20 lb bottle of CO2 and now make my own. I put tap water in the fridge to cool (dissolving gas in water is the opposite to dissolving solids - the colder, the more you can dissolve) and when I need more, I just go out into the shed, inject some CO2, and I am good to go.
What with all the Phthalates in plastic bottles and the lack of any rules governing what is in bottled water, why drink it.

The only way to get anything close to that cost here in OZ is buying buy the crate or buying 5+litre bottles. Considering most of the water I drink is mixed with coffee (to be honest, most days lucky to drink more than a single glass of H2o) I'm not going to be buying in that form.
