Denner vs Migros: Is the Discounter Actually Cheaper?

Updated: September 2026. Sources: RTS, K-Tipp, Beobachter.

Here's a fact that many people living in Switzerland don't know, or tend to forget: Denner is owned by Migros. 100%. Since 2009.

What was once an independent discount chain founded in 1860, the rebel competing against the retail giants, is now a subsidiary of the Migros cooperative federation. Same owner, same industrial infrastructure behind the scenes (since 2014, Denner has had unrestricted access to Migros Industrie supplies), but different brands, different stores and a different promise to customers.

Denner's promise? Always cheaper. The legendary slogan was «Wir sind immer billiger» (we're always cheaper). But in October 2025, the Beobachter published an analysis that caused quite a stir: Denner has become the most expensive of the five major Swiss supermarkets in several independent tests.

How is that possible? And more importantly: is it still worth shopping at Denner instead of Migros?

The backstory you need to know

In 2007, Migros bought 70% of Denner's shares. The official reason? To prevent Aldi or Lidl, which had just arrived in Switzerland, from acquiring the country's leading discount chain. A defensive move that the press called a «brilliant chess move» by Migros.

By 2009, Migros became the 100% owner.

Since then, Denner has remained formally independent in its management, but it sits firmly inside the Migros group. One telling detail: Denner's former CEO, Mario Irminger, became president of the Migros federation's executive board in 2023. Denner was led from January 2025 to the end of April 2026 by Torsten Friedrich, who had previously run Lidl Schweiz; Michel Gruber has been interim CEO since 30 April 2026.

The result is a situation unique to Switzerland: Migros owns both the country's largest supermarket chain and its leading discount store. Two brands from the same group competing on the same shelves.

Is Denner cheaper than Migros? What the baskets show

Not on a standardised basket. In independent tests over the past few years, Denner is no longer the cheapest discounter, and in some cases it lands above Migros: in the RTS test of 30 basic products it came to CHF 181.67 against CHF 170.37 for Migros. K-Tipp found the same direction in October 2024 with 40 products, and the Beobachter picked it up in October 2025. The reason is structural rather than one price tag, and the figures below show where it comes from.

RTS «A Bon Entendeur» test (30 basic products, 2024):

• Lidl: CHF 162.05
• Aldi: CHF 166.59
• Coop: CHF 167.82
• Migros: CHF 170.37
• Denner: CHF 181.67 (the most expensive)

The reason is structural. Denner has a much smaller product range than Migros and Coop, and crucially, it doesn't have a proper budget line comparable to M-Budget or Prix Garantie. When testers look for the cheapest available product, they find M-Budget at Migros and Prix Garantie at Coop, but at Denner they often find only the standard or branded product, which costs more.

In the RTS test, for example, Denner had no budget option for minced meat: testers had to buy the IP Suisse version, which was significantly more expensive, pushing up the total.

K-Tipp test (40 products, October 2024):

The K-Tipp headline read: «Everyday items: Denner more expensive than Coop.» For the first time in K-Tipp's testing history, the Denner basket came in behind Coop's.

Beobachter (October 2025):

The Beobachter wrote bluntly: «Denner is losing its reputation as Switzerland's cheapest retailer.»

The case for Denner

That said, Denner has real strengths that standardised basket tests don't capture well.

Coffee, wine and chocolate. Coffee, chocolate and alcohol are where Denner runs many of its promotions. If you regularly buy coffee or wine, compare Denner's promotions with the other chains' before you shop.

Alcohol and tobacco. Unlike Migros, which has historically refused to sell alcohol in its supermarkets (a principle established by founder Gottlieb Duttweiler and confirmed by 80% of cooperative members in a 2022 vote), Denner sells wine, beer, spirits and tobacco. It's the most visible contradiction in the group: Migros won't sell alcohol on principle, but its wholly-owned subsidiary Denner is one of the largest alcohol retailers in Switzerland.

Store network. With around 872 sales points (612 company-owned and 260 franchise partners, as of 2025), Denner has the densest network among Swiss discounters. Many stores are small and located in residential areas or villages where there's no Aldi or Lidl nearby.

Weekly promotions. Since 5 February 2026, Denner's weekly promotions run Thursday to Wednesday, matching Migros and Coop. Brand-name promotions can be very worthwhile.

The case for Migros

Budget staples with M-Budget. M-Budget covers hundreds of everyday products at prices that often rival Aldi and Lidl. M-Budget butter at CHF 2.95, milk at around CHF 1.03/L, spaghetti at CHF 1.20/kg. Denner simply doesn't have an equivalent at these prices.

Product range. A mid-sized Migros store carries 10-15 times more products than a Denner. Fresh fruit and vegetables, regional products, specialty lines: Migros has everything under one roof.

Cumulus. Migros' loyalty programme has over 2 million members and offers personalised vouchers. Denner has no loyalty programme of its own.

The Tiefpreis programme. In 2025, Migros cut prices on 3,500 products by an average of 10%, further narrowing the gap with discounters.

So, Denner or Migros?

It depends on what you buy and how you shop.

Choose Denner if you regularly buy coffee, wine or chocolate on promotion, if you need alcohol or tobacco, if the nearest Denner is more convenient, or if you prefer a quick shop in a small store.

Choose Migros if you do a full weekly shop for the family, if you use M-Budget for staples, if you want a wide range including fresh produce and specialties, or if you use the Cumulus programme.

The smartest strategy? Use both. Buy your staples at Migros with M-Budget, and stop at Denner when there's a good promotion on coffee, wine or branded products. They're part of the same group, and you'd almost think they were designed to complement each other. In practice, that's exactly how many Swiss households shop.
