Sir; As a consumer, I take issue with your findings ('The Grocer 33 annual review', The Grocer,).

Many will agree with me that Asda is not the cheapest super­market when measured against discounters such as Lidl, Aldi and Netto, which are cheaper. Furthermore, they both have hundreds of stores in Britain, Europe, the US and Latin America.

The retailer brands are different, but it's the same product you're paying for. Millions use Lidl and Aldi every year, yet you overlook them.
