Major Supermarkets in Ireland

The main supermarket chains in Ireland include:

1. Aldi
2. Lidl
3. Tesco
4. Dunnes Stores
5. SuperValu

Each of these chains has its own strengths, from budget-friendly private labels to extensive product ranges. But how do they compare on price?

Price Comparison Methodology

To determine the cheapest supermarket, we created a shopping basket of 20 commonly purchased items, including:

• Bread (sliced white loaf)
• Milk (2L full-fat)
• Eggs (dozen free-range)
• Chicken fillets (1kg)
• Bananas (1kg)
• Potatoes (2.5kg)
• Pasta (500g)
• Canned tomatoes (400g)
• Cheddar cheese (200g)
• Butter (250g)
• Breakfast cereal (e.g., cornflakes, 500g)
• Tea bags (80-pack)
• Coffee (instant, 100g)
• Toilet paper (4 rolls)
• Toothpaste (100ml)
• Laundry detergent (1L)
• Cooking oil (1L)
• Chocolate bar (100g)
• Crisps (6-pack)
• Wine (750ml, house brand)

We visited multiple branches of each supermarket chain in January 2025 to collect prices. The goal was to ensure consistency and account for regional pricing differences. Additionally, we compared promotional deals and analyzed the impact of loyalty programs.

Results of the Price Comparison

Here are the total costs of the shopping basket at each supermarket:

• Aldi: €42.50
• Lidl: €43.00
• Tesco: €47.20 (using Clubcard prices)
• Dunnes Stores: €48.30 (with vouchers applied)
• SuperValu: €50.10

Key Observations

1. Aldi emerges as the cheapest option, offering excellent value for essential items like bread, milk, and eggs. Their private-label products are consistently affordable without compromising on quality.
2. Lidl follows closely, often matching Aldi on staples but slightly higher on items like wine and laundry detergent. However, Lidl sometimes offers bulk discounts that could bring its costs below Aldi for specific purchases.
3. Tesco benefits from its Clubcard loyalty program, which offers significant discounts on many products. For example, the Clubcard price for tea bags and coffee was nearly 20% lower than the standard shelf price. Without the Clubcard, Tesco’s prices would be less competitive.
4. Dunnes Stores relies heavily on its voucher system (e.g., €10 off when you spend €50), making it a good choice for larger shops. For example, applying a voucher to a basket of non-perishable items significantly reduced the average cost per item.
5. SuperValu is the most expensive, likely due to its emphasis on local Irish products and premium branding. However, its Real Rewards program provides points that can be redeemed for discounts, partially offsetting its higher prices.

Deeper Insights into Price Differences

• Fresh Produce: Aldi and Lidl dominate in this category with consistently lower prices on staples like bananas, potatoes, and carrots. For instance, Aldi’s 1kg bananas cost €1.19 compared to €1.49 at Tesco.
• Branded Items: Tesco and SuperValu offer a wider selection of branded products. However, these items are usually more expensive than Aldi or Lidl’s private-label equivalents.
• Household Essentials: Toilet paper and cleaning supplies were cheapest at Aldi and Lidl, with similar quality to more expensive branded options at Tesco and Dunnes.
• Alcohol: Aldi and Lidl’s house-brand wines and beers are budget-friendly and highly rated, often undercutting competitors by €2-€3 per bottle.

Other Factors to Consider

While price is a crucial factor, it’s worth considering other aspects that might influence your decision:

• Product Quality: Aldi and Lidl’s private labels are highly rated, but Tesco and SuperValu often stock a wider range of premium and branded products. For example, Tesco’s Finest range offers high-end alternatives that may appeal to gourmet shoppers.
• Store Accessibility: SuperValu and Tesco often have more locations, making them convenient for many shoppers. Aldi and Lidl, while cheaper, may not be as widely available in rural areas.
• Loyalty Programs: Tesco’s Clubcard and Dunnes’ vouchers can lead to significant savings over time. For instance, a shopper spending €100 weekly at Tesco could save up to €200 annually with Clubcard deals.
• Sustainability: Lidl and Aldi have strong sustainability initiatives, including reducing plastic packaging and supporting local suppliers. This might appeal to environmentally conscious consumers.

Why Aldi is the Best Choice for Budget Shoppers

Aldi’s pricing strategy is straightforward: keep costs low while maintaining quality. Their streamlined store layout, limited product range, and focus on private-label goods allow them to pass savings on to customers. This makes Aldi the top choice for those looking to maximize their grocery budget. Moreover, Aldi’s frequent special buys and weekly deals add further value for cost-conscious shoppers.

Tips for Saving Even More

Regardless of your supermarket choice, here are some tips to save on your grocery bills:

• Plan Your Meals: Create a weekly meal plan and stick to it.
• Buy in Bulk: Items like pasta, rice, and canned goods are often cheaper in larger quantities. For example, Lidl’s bulk pasta packs cost 15% less per gram compared to smaller packs.
• Use Loyalty Programs: Sign up for Clubcard or Dunnes’ loyalty programs to take advantage of discounts and rewards.
• Shop Off-Peak: Many supermarkets offer discounts on perishable items in the evening. For example, Tesco often marks down bakery items by up to 50% after 6 PM.
• Embrace Private Labels: Store-brand products are often as good as, if not better than, branded alternatives. Aldi’s private-label butter and milk, for example, consistently rank high in taste tests.

Conclusion

For most Irish shoppers, Aldi is the cheapest supermarket, offering unbeatable prices on everyday essentials. Lidl’s comparable pricing and Tesco’s loyalty discounts make them strong contenders depending on your shopping habits. However, for those prioritizing premium products or convenience, Tesco and SuperValu remain viable options despite higher costs.

After conducting a thorough comparison, it is clear that Aldi consistently offers the lowest prices across a wide range of everyday essentials. Aldi’s focus on private-label products and its commitment to keeping operational costs low allow it to pass on significant savings to customers. Whether it’s staples like bread and milk or household items such as detergent and toilet paper, Aldi frequently outperforms its competitors in terms of affordability.

Lidl, while slightly more expensive than Aldi, remains a close competitor and is an excellent choice for shoppers seeking similar value. Lidl’s promotional discounts and occasional bulk deals may even allow savvy shoppers to match or beat Aldi’s prices on certain items.

Tesco stands out for its extensive range of branded products and its Clubcard loyalty program, which offers impressive discounts on select items. For shoppers who prefer branded goods or are willing to plan their purchases around Clubcard deals, Tesco can still be a competitive option.

Dunnes Stores and SuperValu cater to shoppers who prioritize premium products and local Irish brands. Dunnes’ voucher system and SuperValu’s Real Rewards program can help mitigate higher prices, especially during larger shopping trips. However, these chains remain more expensive for day-to-day shopping.

Ultimately, the answer to “Which is the Cheapest Supermarket in Ireland?” depends on your shopping habits and priorities. For budget-conscious shoppers, Aldi is the clear winner, offering the lowest overall costs without sacrificing quality.
