Choosing a Spanish supermarket, Mercadona, Carrefour, Lidl, Dia and others

Key rules

• Default choice: Mercadona is the biggest chain and is nearly everywhere, so it is the easiest first choice for low prices and steady quality.
• Second shop: Add a second shop for what Mercadona lacks, such as Carrefour or Alcampo for range and bulk, or Lidl for bakery and German goods.
• Regional chains: Local chains such as Consum, Eroski, Gadis or Ahorramas are strong only in their own regions.
• Budget: Mercadona, Dia and Lidl are often among the cheaper chains, but your bill depends on household size, city and brands.

The short answer

Start with Mercadona. It is the biggest chain in Spain, it is almost everywhere, and it is a safe default for low prices and steady quality. Then add a second shop for what Mercadona does not stock. Which one depends on where you live and what you miss.

Mercadona: your default

Mercadona sells mostly its own brands: Hacendado for food, Deliplus for beauty, Bosque Verde for household goods and Compy for pets. Most shelves hold only one or two options per product, so shopping is quick.

• It has about 1,500 products, against over 10,000 in a hypermarket.
• Most stores have a bakery, fresh counters and ready meals.
• It has no loyalty card and few promotions. Prices are meant to be low every day.
• Many stores have smart checkout, and online shopping is available in many areas.
• Few big brand names are stocked, though some, such as Coca-Cola, Nescafé and Danone, are there.

Choose it if you want simple, cheap and consistent. Look elsewhere if you need a specific foreign brand or non-food items.

The other national chains

• Carrefour: second in size. It runs hypermarkets with a wide range, including non-food and international brands. Good for a big monthly shop or hard-to-find items.
• Lidl: good for cheap basics, bakery and German specialities.
• Dia: many small neighbourhood stores and franchises. Handy if you want something close to your door.
• Alcampo: hypermarkets and supermarkets, strong for buying in bulk.
• Aldi: smaller, with a discount format.
• El Corte Inglés and Supercor: the premium option.
• Eroski: strong in the north.

Regional chains

In some regions a local chain is the main alternative. Check which ones are near you:

• Valencia, Murcia, Castilla-La Mancha, Aragón: Consum. Family Cash is also in Valencia and Murcia.
• Basque Country, Navarra, Galicia, Balearics: Eroski. BM is in the Basque Country.
• Galicia, Asturias, León: Gadis. Froiz is in Galicia and Alimerka in Asturias and León.
• Catalonia: Bonpreu/Esclat, Caprabo and Condis. Caprabo also has some stores in Navarra and the Balearics.
• Madrid: Ahorramas.
• Andalusia: Supersol, Dani Hijos and Cash Fresh.
• Canary Islands: Spar and Hiperdino.

Mercadona and Lidl are found nearly everywhere, so they work wherever you land.

How to choose

1. Look at what is within walking distance. A shop you can reach easily beats a cheaper one you avoid.
2. Match the shop to your needs. Choose Mercadona for everyday basics, Carrefour or Alcampo for variety and bulk, and Lidl for bakery and German products. Choose Dia or a local chain for quick top-ups.
3. Think about budget. Mercadona, Dia and Lidl are often among the cheaper chains. A couple's food budget is usually a few hundred euros a month, and it rises with household size, city and how much you buy by brand. Valencia, Alicante and Murcia have often been among the cheaper cities.
4. Try two for a month. Keep the receipts, compare, and settle on one main shop plus one backup.

Everyday habits such as weighing vegetables, bags and own-brand products are covered in the quick answers below.

Quick answers on supermarket habits and own-brand products

Do I weigh my own vegetables in a Spanish supermarket?

It depends on the chain: in Carrefour, Alcampo, Eroski, Lidl and Dia you usually weigh and label loose produce yourself. Pick the item on the scale screen and a price sticker prints, which is scanned at the till. In Mercadona, produce is mostly pre-packed or weighed by staff at the checkout.

Do Spanish supermarkets charge for bags?

Yes, supermarkets charge for bags, and reusable ones usually cost from a few cents to about 0.5 euro depending on type. Paper bags cost a few cents and heavy reusable bags cost more. Thin fruit bags must be compostable or recycled, also for a fee, so many people bring their own.

Is own-brand food (marca blanca) worth buying?

Yes, own-brand products are one of the easiest ways to cut your grocery bill, such as Hacendado, Carrefour or Dia own labels. Compare the unit price per kg or litre on the shelf label to see the real saving. Reduced end-of-day items are another cheap option.

Why is most milk in Spain sold unrefrigerated?

Most milk in Spain is UHT (long-life), so it sits on ordinary shelves because it keeps unopened without a fridge. It became the habit because of the warm climate, long distances and a historically weak cold chain, and it is cheap. Fresh pasteurised milk exists but lasts only a few days and is mainly in the fridge section of larger supermarkets, especially in the north.
