Confused about bottled water?

Well, prepare to be even more so...Pepsi are going to try and sell us empty bottles. Apparently, in countries where the water supply is a high enough standard, Pepsi will be marketing sterilised, hermitically sealed empty bottles to allow us to fill and refill them from our own taps as often as we wish - it'll be cheaper because it's cutting out the "bottling costs". No shit, sherlock.
