If inflation is only about 3 per cent, can someone please explain how the standard price of a Co-op one-litre carton of orange juice has just risen from 42p to 54p, an increase of 12p or more than 25 per cent?

I can imagine the hilarity with which my employer would greet my request for a pay rise of similar proportions. This is just corporate greed.
