xoc, the names of commenters are at the bottom of their comments, not the top. The commenter you were responding to was actually Buzzcut, not Eliezer.

Buzzcut, if you pay more for water than you do for gasoline, I want to suggest you find a cheaper source for your water. I can buy certified water in gallon jugs for not much over $1/gallon, but gasoline here is $3/gallon. I can get water cheaper in larger quantities, and I could buy a cheaper brand but then I find myself wondering about the certification. Kind of like buying the cheapest gasoline....
