I was at the "elephant" supermarket to buy some drinking water and made the following observation:
The 1 litre "blue label" water packed for the supermarket by aquamist "somewhere in the rift valley" costs 38 bob and is called spring water whereas the aquamist branded one called mineral water costs 65 bob..What is the difference??

Can someone also explain to me why the "blue" packaged products i.e TP ,sugar,rice etc..are cheaper than the branded ones..is it that the retailer buys the stuff in bulk and then repackages it or is there something else?
