It's amazing what some people will pay for water. I work for a beer distributor, we also have some high-end waters. Both Icelandic Glacial and Mountain Valley Spring Water go for about $20 for a 24 pack of .5 ltr pet. It sells, even in an area where sanitized and filtered Lake Michigan (fresh) water is the primary source. I just don't get it...I heart my tap water.
...or maybe I'm just cheap...
Peace,
Bob
