The best supermarkets in Switzerland depend on what matters most to you. Coop is a strong fit for broad choice and sustainable or organic ranges, while Migros combines a large everyday range with alcohol-free supermarkets. Denner, Aldi Suisse, and Lidl Schweiz are discount-focused alternatives. There is no supermarket that is automatically cheapest for every basket because own-label prices and weekly promotions vary. This guide compares the five chains by format, current network size, shopping strengths, loyalty tools, and online availability so you can choose the right store for the way you actually shop.

Key takeaways

• Coop and Migros remain the two major full-range Swiss supermarket groups, but discount chains are important alternatives for price-focused shopping. [1] [3]
• Coop reported 982 supermarkets at the end of 2025 and CHF 6.9 billion in net sales from sustainable ranges. [1] [2]
• Migros supermarkets remain alcohol-free following the 2022 cooperative-member vote. [6]
• Denner reported 872 locations in 2025, while Aldi Suisse reports more than 245 stores and Lidl Schweiz more than 190. [5] [7] [8]
• For price comparisons, check unit prices, budget own labels, and the current week’s promotions instead of assuming one chain is always cheapest.

Best supermarkets in Switzerland: Quick comparison

Coop: Broad choice and a sustainability focus

Coop reported 982 supermarkets at the end of 2025, up from 970 a year earlier. The supermarkets, including Coop.ch, generated CHF 12.4 billion in net sales in 2025. [1]

Its sustainable ranges generated about CHF 6.9 billion in net sales in 2025. Coop also reported more than 21,600 articles in its sustainable range and CHF 2.4 billion in Group-wide organic sales. [2]

For shoppers, the practical advantage is range: Coop combines national brands, own labels, organic and certified products, and the lower-priced Prix Garantie line. That breadth makes it useful when you want to complete most of a shopping list in one store rather than optimize every item for the lowest possible price.

Migros: Everyday range, own brands, and alcohol-free supermarkets

Migros reported CHF 31.9 billion in Group sales for 2025. Its supermarket business, which includes Migros supermarkets, Migros Online, VOI, and M-Partner, generated consolidated sales of CHF 12.653 billion. [3] [4]

For the M, MM, and MMM supermarket formats, Migros reported 659 locations in 2025. Migros also said permanent price reductions on more than 1,000 everyday products contributed to higher sales volumes during the year. [3]

Migros supermarkets remain alcohol-free. Cooperative members in all ten regional cooperatives voted in 2022 to retain the ban on alcoholic-beverage sales. [6]

The M-Budget range gives price-conscious shoppers an entry-price option without leaving the Migros network, while Cumulus provides points, vouchers, and digital coupons for repeat customers.

Denner: Discount shopping and weekly promotions

Denner remains part of the Migros Group but operates as a discount retailer with its own store network and assortment. In 2025, Denner reported net sales of about CHF 3.9 billion, 612 Denner branches, and 260 Denner Partner stores. That gives it a total network of 872 locations. [5]

Denner works best when its current offers match the products on your list. A discount label alone does not guarantee that every individual product will cost less than the equivalent item at Migros, Coop, Aldi, or Lidl.

Aldi Suisse: Discount pricing with a national network

Aldi Suisse is another major discount option for shoppers who put everyday value ahead of having the widest possible assortment. Aldi’s current corporate information reports more than 245 stores across Switzerland. [7]

The main trade-off is straightforward: a more focused discount assortment can make price-led shopping simpler, but a full-range Coop or Migros may offer more choice within individual categories. For a fair comparison, build the same basket at each chain and compare the unit price per kilogram, litre, or item rather than package price alone.

Lidl Schweiz: Discount shopping plus Lidl Plus

Lidl Schweiz reports more than 190 stores across Switzerland. Like Aldi, it operates with a discount-focused model rather than trying to match the assortment breadth of the biggest full-range supermarkets. [8]

Lidl also uses Lidl Plus as a loyalty and digital-offers platform. The Swiss program provides offers and coupons, digital receipts, and a points function that can be used across Lidl Switzerland stores. [10]

Which supermarket is cheapest in Switzerland?

There is no reliable permanent winner because the result changes with the products in your basket, package sizes, own-label choices, and weekly promotions. Aldi Suisse, Lidl Schweiz, and Denner operate as discount formats, while Migros and Coop compete partly through entry-price ranges such as M-Budget and Prix Garantie.

Use this four-step comparison instead:

• Compare unit price: use CHF/kg, CHF/litre, or the equivalent unit rather than package price.
• Compare like with like: put budget own labels against similar budget products, not against premium brands.
• Separate normal prices from promotions: a one-week discount does not show which store is cheaper long term.
• Include convenience: a small saving may disappear if another supermarket requires extra travel or a second shopping trip.

What does 2026 customer satisfaction show?

Price is only one measure of a supermarket. In a representative Swiss retailer customer-satisfaction survey published by Moneyland in July 2026, Migros scored 7.6 out of 10 and Coop 7.4. Lidl Schweiz scored 7.2, Denner 7.1, and Aldi Suisse 7.0. [9]

Those scores should not be treated as a price ranking. They are useful because they show that shoppers also judge retailers on factors beyond the checkout total, including the overall shopping experience and how well a chain meets their needs.

Loyalty programs

Coop Supercard and Migros Cumulus are major loyalty programs for their respective supermarket ecosystems. Cumulus includes points, vouchers, and digital coupons, while Coop uses Supercard points and digital offers.

Lidl Plus adds offers, coupons, digital receipts, and loyalty points for Lidl shoppers. [10] Denner places more emphasis on current promotions and weekly offers. Loyalty benefits are most valuable when you already shop regularly at the same chain; they should not replace a direct unit-price comparison.

Online grocery

Coop operates Coop.ch and Migros operates Migros Online. Coop reported that Coop.ch net sales grew by 10.2% in 2025, while Migros Online generated CHF 362 million in sales during the year. [1] [3]

Delivery slots, fees, pickup options, and available products can vary by address, so check the service at checkout before relying on either one for a weekly shop.

How should you choose between Coop, Migros, Denner, Aldi, and Lidl?

• If you want broad choice plus a large sustainable and organic range, start with Coop.
• If you want a broad everyday range, own brands, and alcohol-free supermarkets, try Migros.
• If you want to build your shop around weekly discount offers, check Denner.
• If your priority is a discount-format shop for everyday staples, compare Aldi Suisse and Lidl Schweiz.
• If loyalty-app discounts matter to you, compare Supercard, Cumulus, and Lidl Plus before deciding where repeat shopping delivers the most value.

FAQs

What are the main supermarkets in Switzerland?

Coop and Migros are the two major full-range supermarket groups, while Denner, Aldi Suisse, and Lidl Schweiz are important discount-focused alternatives. Other regional and specialist retailers also operate in Switzerland, but these five chains cover the main choices most shoppers compare when deciding between range, convenience, promotions, and price.

Which supermarket is cheapest in Switzerland?

There is no supermarket that is cheapest for every basket. Aldi Suisse, Lidl Schweiz, and Denner use discount-focused formats, while Migros and Coop offer lower-price own-label ranges. Compare the same products, package sizes, unit prices, and current promotions in the same week instead of relying on a permanent cheapest-store ranking.

Is Migros cheaper than Coop?

It depends on the basket. Migros has M-Budget and Coop has Prix Garantie, and both retailers change prices and promotions over time. The useful comparison is the unit price of the products you regularly buy. A single product or promotional week is not enough to prove that one chain is always cheaper overall.

Does Migros sell alcohol?

Migros supermarkets do not sell alcoholic beverages. Members of all ten regional Migros cooperatives voted in 2022 to retain the existing alcohol-sales ban. That policy distinguishes Migros supermarkets from Coop and discount chains such as Denner, Aldi Suisse, and Lidl Schweiz when alcoholic drinks are part of the shopping list.

Do Coop and Migros offer online grocery delivery?

Yes. Coop operates Coop.ch and Migros operates Migros Online. Both provide online grocery shopping, but the exact product selection, delivery windows, pickup choices, fees, and service availability can depend on the delivery address. Check your postcode or address on the retailer’s checkout system before planning a full online grocery order.

Which Swiss supermarket should you choose?

For the broadest one-stop comparison, start with Coop or Migros: Coop is particularly strong in sustainable and organic ranges, while Migros combines a broad everyday assortment with alcohol-free supermarkets. Choose Denner when its weekly offers fit your list, and compare Aldi Suisse and Lidl Schweiz when a discount-format shop is the priority. No chain wins every basket, so the most reliable next step is to compare the unit prices of the products you buy most often and then factor in promotions, loyalty benefits, and travel convenience.
