> Many people drinking bottled water aren't drinking the cheapest in the supermarket - the recycling bin outside my flat is regularly filled with 1.5l evian bottles - they're £1 each in the local shop. At one bottle a day, that's ~35 person-years. Not common, but not insane. Even given expensive name brand water, a $50 filter cartridge only lasts for six months. That's $3150 for the same period. $50 replacing $25,000 is not grounded in reality.
