An article by G.E. Miller from 20 Something Finance pointed out that you could fill 4,787 water bottles with tap water for $2.10. That’s right, $2.10. So let’s say you buy bottled water 5 times a week at a $1, not only are you buying the equivalent of over 9,000 bottles of tap water a week, you are spending $260 per year that could be used to have an over flowing investment account. Better yet, invest into Pepsi, Coke, Danone, Nestle, or one of the other companies that have figured out that selling us tap water, is pretty good business.
