THE cheapest supermarkets in the country are to be found in Granada and Jaen.
The Granada-based chain Dani Supermarkets consistently provides the lowest prices, according to a report by the Organisation of Consumers.
The supermarket opened its first shop in Granada city in 1959 and its first supermarket in 1971.
In 2003 it opened a series of stores in Malaga.
Meanwhile for its own-branded items Lidl came in as the least expensive followed by Alcampo, Carrefour and Aldi.
At the opposite end of the scale the most expensive place for food shopping nationally was in El Corte Ingles where the prices were nearly 25 per cent higher than its main rivals.
According to the study, the average family could actually save up to 1300 euros a year just by knowing where shop.
