>>TESTING HOW STORES PERFORM ON A THEMED SHOPPING BASKET

At £10.88, Asda in Cwmbran checked in the cheapest of three full baskets as our shoppers searched the chillers for 10 dairy products. Somerfield in Stirling charged £11.00, Waitrose £11.85.

The average price of the full dairy list fell 2% compared to our last visit in July, due in part to a 6% fall in the price of Cathedral City cheese, with Actimel down 5% and Philadelphia down 3.45%, while Anchor Spreadable rose 3.2%. Somerfield in Stirling had the best priced pre-packed Cathedral City at £1.23, while its Stretford store only sold the cheese at the deli counter but had knocked it down 33% a kilo. Asda in Cwmbran had an end-of-aisle free-standing chiller to promote the branded cheese and had the lowest priced fresh cream at 47p.
