Plastic bottle water expires every year.  So you will have to replace your one bottle of water for a new bottle each year.  If each bottle costs you 50 cents, that would cost you $25 over the period of 50 years.  That easily costs 6 times more than one can of Blue Can Water.  Furthermore, the cost might be even higher as it's likely that the cost of new bottled water will increase over the years.  Buy Blue Can Water, and save the pain and hassle of having to replace your bottled water.  Also to avoid the problem of not being able to get water if there's a water emergency.
