ose hazy, shady days back in the 70s, the age of three-day weeks, galloping inflation, flairs and the Bay City Rollers, it was commone to find quite a collection of price stickers on tins, boxes, and packets on supermarket shelves. One on top of the other. Always in an upward spiral. The practice was outlawed by an Act of Parliament that stipulated that once an item was on the shelf, it couldn't be re-priced.

Every supermarket chain in the country is systematically flouting the law. Using modern technology, pressing a button on a central computer, can change the price of every pint of milk, or whatever, from John O'Groats to Land's End. Why are Trading Standards Departments and the Government not acting to close this loophole?
