Six litres of milk, a kilo of chicken, some fresh fish, yoghurts, soft drinks, toilet paper, shower gel, laundry detergent, fruit and vegetables, among other products, are included in the weekly shopping basket of the average family in Spain.
But depending on the supermarket chain and the city or town where the purchase is made the price difference can be up to 30 per cent between the cheapest and most expensive.
That is according to the annual study of supermarkets carried out by the Organisation of Consumers and Users throughout Spain. For the reports preparation, OCU representatives visited 1,103 establishments in 65 cities and towns (in addition to trawling internet sites) and analysed 160,976 prices in a shopping cart with 238 products from various categories.
The average saving that could be achieved nationally this year reached 1,073 euros, 10.5 per cent more compared to 2020.
The Alcampo de Murcia hypermarket is the cheapest supermarket in Spain while on the flip side of the coin is the Sánchez Romero supermarket, in La Moraleja (Madrid).
The city where there is a greater opportunity to save up to 3,532 euros is Madrid, thanks to the greater diversity of commercial offerings that large cities have.
On the contrary, the town where it is only possible to save 325 euros for a whole year by shopping at the cheapest establishment is Puertollano.
In Andalucía, that saving is 928 euros, a figure well below the average for Spain and where Cadiz is the city where it is more difficult to save – with only a 574 euro difference between the most expensive establishment and the cheapest one. Seville, on the other hand, with 1,468 euros, is where there is more room for easing the pressure on the pocket.
Malaga and Marbella are the two Andalusian locations where it can cost the most to do the shopping. However, they are also the two (after Seville) where the consumer has the best chance of making savings, with 1,099 euros in Malaga and 1,130 in Marbella.
In Andalucía, the Covirán store on Calle Fray Marcos de Niza street in Seville city is the most expensive place, followed by the Supercor establishments in Malaga and Marbella.
By chains, the two most competitive in the country can be found in Andalucía. For another year it is Dani and then Más Ahorro, followed nationally by Family Cash and Tifer, as the most affordable. At the other end of the scale the Sorli Discau and Supermercado Plaza chains come out as the most expensive.
The OCU study emphasises the disparity in the cost of the shopping basket that exists between cities and regions. The Valencian region together with that of Murcia are the two where the pocket is least hit when filling the shopping trolley. In contrast, the Balearic Islands are the most expensive, followed by the Canary Islands, the Basque Country and Catalonia. Andalucía is among the cheapest regions, standing out especially in fresh products, where it obtain the best ranking of them all.
By cities, Jerez de la Frontera is the cheapest in Andalucía with an index of 100. It is followed very closely by Almeria, with an index of 101. Next are Huelva and Granada with 102. Cadiz, Córdoba and Seville have an index of 103. Jaén follows with 104, and finally Malaga city and the town of Marbella top the table for the most expensive to do the weekly shop.
