Fighting back against supermarkets

Plastered all over our nearest asda store are the green pos (point of sale) cards claiming big savings.
Last week, the "natural fit nappies" that we normally get had been removed from the shelves and the "offer" budget nappies - increased in price to the price of the normally more expensive "natural fit" nappies - were plastered all over. Lack of availability for nappies not included in the "sale" and a price increase on the budget nappies that were advertised as being in the "asda baby event"

Formula baby milk, numbers 1,2 and 3 have gone up by more than the rate of the VAT increase, so much so that if you buy one box per week for a year, you will be paying out more than £10 EXTRA! (They have no VAT on them anyway!)

How asda are allowed to get away with having a promotion called a "baby event" at the same time as asda INCREASE the prices of regular weekly baby products, is a disgrace. It should be stopped!
