Sue Davies, Which? Head of Food Policy and Consumer Rights, said: "It is good to see food retailers making commitments to keep food prices low for consumers, however it is important that this does not come at the expense of other factors such as quality. "Which? is calling on supermarkets to be more transparent about costs and provide clear unit pricing to help shoppers to easily compare items. Budget ranges must also be more widely available across stores, so people do not have to pay over the odds for everyday essentials." -ENDS-
