Spain’s two dominant budget supermarket chains, Mercadona and Dia, offer genuinely good quality food at prices that make self-catering during a Spain trip a real budget strategy rather than a compromise. This is exactly what £12 a day buys.
Quick answer: £12/day at Mercadona or Dia covers three proper meals plus snacks for one person, based on a mix of fresh produce, prepared items, and Spain’s genuinely excellent value bakery and deli sections. This runs roughly 60-70% cheaper than eating three meals at restaurants throughout a Spain trip.
A Full Day’s Mercadona/Dia Shop
| Meal | Items | Cost (EUR) | Cost (GBP) |
|---|---|---|---|
| Breakfast | Fresh bread roll + jamón + orange juice | €2.50-€3.50 | £2.15-£3 |
| Lunch | Tortilla española slice + mixed salad + fruit | €3-€4 | £2.55-£3.40 |
| Dinner | Fresh fish or chicken + vegetables + bread | €5-€7 | £4.30-£6 |
| Snacks | Yoghurt + nuts or fruit | €1-€1.50 | £0.85-£1.30 |
| Total | €11.50-€16 | £9.80-£13.70 |
Mercadona: Spain’s Genuinely Excellent Budget Chain
Mercadona has built a reputation, both among locals and increasingly international visitors, for quality that noticeably outpaces its budget positioning, particularly in its prepared food and bakery sections.
- Hacendado (Mercadona’s own brand): consistently praised for quality-to-price ratio, spanning everything from olive oil to prepared meals
- Fresh bakery section: bread rolls from €0.40-€0.80 (35-70p), genuinely good quality rather than the mass-produced sliced bread stereotype of budget supermarkets elsewhere in Europe
- Prepared tortilla española: €3-€5 (£2.55-£4.30) for a substantial pre-made portion, a genuine time-saver for lunch or dinner without any cooking required
- Jamón serrano (sliced, packaged): €1.50-€3 (£1.30-£2.55) for a generous pack, one of the best-value protein sources in any Spanish supermarket
Dia: The Even Cheaper Alternative
Dia positions itself as Spain’s discount supermarket chain, running slightly below Mercadona on price across most categories, though with a somewhat narrower selection.
- Own-brand pasta, rice, and canned goods: consistently the cheapest baseline prices among Spain’s major chains, useful for anyone genuinely self-catering rather than mixing in prepared items
- Fresh produce: generally good quality, though selection varies more by specific store location than Mercadona’s more standardised approach
- Frequent promotional discounts: Dia runs more aggressive short-term promotions than Mercadona, worth checking the weekly flyer (available in-app) for genuine savings on specific items
The honest verdict on Mercadona vs Dia: Mercadona edges ahead on overall quality and consistency, particularly for prepared foods, while Dia wins on baseline pricing for straightforward staples. Many budget-conscious travellers use both, Mercadona for fresh and prepared items, Dia for pantry basics.
Lidl: The Third Option Worth Considering
Beyond Mercadona and Dia, Lidl operates extensively throughout Spain and offers a genuinely competitive alternative, particularly strong on bakery items and weekly rotating non-food promotions. Its pricing generally sits between Mercadona and Dia, though its fresh produce selection varies more by individual store than either of the two Spanish-origin chains. For travellers moving between multiple towns during a trip, checking which of the three chains has the most convenient location often matters more than any meaningful price difference between them.
Building a Genuinely Good Day of Meals
Spanish supermarket culture leans naturally toward fresh, minimally processed eating, making a genuinely balanced day easier to build than in some other countries’ budget supermarket ecosystems.
- Breakfast: fresh bread with jamón or a simple tomato rub (pan con tomate, genuinely a Spanish breakfast staple) plus fruit
- Lunch: a cold option built around tortilla española, a mixed salad, and bread, ideal for eating on the go or at accommodation without cooking
- Dinner: fresh fish (often available pre-marinated or ready to pan-fry) or chicken with vegetables, requiring minimal cooking equipment beyond a single pan
What This Actually Saves Compared to Restaurant Dining
| Category | Supermarket (per day) | Restaurant Dining (per day) |
|---|---|---|
| Breakfast | £2.15-£3 | £4-£7 |
| Lunch | £2.55-£3.40 | £8-£14 |
| Dinner | £4.30-£6 | £15-£25 |
| Total | £9-£12.40 | £27-£46 |
Self-catering cuts daily food costs by roughly 65-70% compared to eating every meal at restaurants, without sacrificing much in freshness or quality given Spain’s strong supermarket produce and deli culture.
Step-by-Step: Making This Budget Work
- Book accommodation with at least basic kitchen access (a fridge and one hob ring is genuinely enough) to make self-catering practical rather than relying entirely on cold, ready-to-eat items.
- Shop at Mercadona for prepared and fresh items, Dia for pantry basics, if both are accessible, to maximise the value split between the two chains.
- Check the Mercadona and Dia apps for the current week’s promotional flyer, since both run genuine, meaningful discounts on rotating items worth planning meals around.
- Buy bread daily rather than in bulk, since Spanish bakery bread doesn’t keep well and fresh purchases cost little enough that daily buying isn’t a meaningful expense.
- Balance self-catering with one or two restaurant meals during the trip, since Spain’s tapas and dining culture is genuinely worth experiencing, and this budget approach frees up funds specifically for that rather than eliminating it entirely.
Frequently Asked Questions
Is Mercadona more expensive than Dia overall?
Slightly, though the gap is narrow and Mercadona’s stronger quality on prepared and fresh items often justifies the modest price difference for travellers prioritising convenience alongside cost.
Can you eat well at Spanish supermarkets without any cooking equipment at all?
Yes, reasonably well. Pre-made tortilla, sliced jamón, fresh bread, cheese, and fruit all require zero preparation, making a genuinely satisfying no-cook diet achievable, though a single hob ring meaningfully expands the options available.
Are Mercadona and Dia available throughout Spain, including smaller towns?
Mercadona has a broader national footprint including many smaller towns, while Dia’s presence is more concentrated in larger towns and cities, worth checking availability for the specific region being visited.
How does this compare to eating at a Spanish menu del día (fixed lunch menu)?
A menu del día, Spain’s fixed-price lunch offering (typically €10-€15/£8.55-£12.80 for a starter, main, and drink), remains genuinely good value compared to standard restaurant dining, though supermarket self-catering still runs noticeably cheaper across a full day.
Are Mercadona and Dia open on Sundays?
Coverage varies by region and specific store, since Sunday trading hours are regulated differently across Spain’s autonomous communities. Checking the specific store’s hours via the app before planning a Sunday shop avoids an unexpected closure.
Do Mercadona and Dia carry gluten-free or other dietary-specific products?
Yes, both chains carry a reasonable range of gluten-free, lactose-free, and vegetarian own-brand products, with Mercadona’s selection generally somewhat broader given its wider overall product range. Checking labels remains sensible for anyone with specific dietary needs, since not every product line is clearly marked in English.
The Bottom Line
Spain’s Mercadona and Dia supermarkets deliver genuinely good, fresh food at prices that make £12/day self-catering a realistic, enjoyable strategy rather than a joyless budget compromise. The honest approach for most travellers combines this with the occasional restaurant meal or menu del día, using the supermarket savings to fund the dining experiences genuinely worth paying for.
