If you live in Switzerland, you already know the drill: you're either a Migros person or a Coop person. Some people have been shopping at Migros their entire lives. Others swear by Coop and always have their Supercard handy. And plenty of people just walk into whichever store happens to be closest.
But when it comes down to the numbers, which one is actually cheaper?
What is the difference between Coop and Migros?
On price, the difference sits in the own-brand lines. Across the 10 staples checked in June 2026, Migros' M-Budget is lower than Coop's Prix Garantie on seven: milk is 12% less per litre, butter 16% less, spaghetti 33% less. On branded goods the chains are mostly level: in August 2025 bonus.ch found mostly identical prices at Aldi, Coop, Lidl and Migros, with a largest gap of 30 centimes. Coop is lower on budget chicken breast, CHF 11.50 per kilo against roughly CHF 13.80, and in promotion weeks the picture can shift on individual products at either chain. Dark bread is CHF 1.00 in both chains.
To find out, we picked 10 products that end up in almost every shopping cart: milk, butter, bread, eggs, pasta, chicken, coffee, cheese, yoghurt and Coca-Cola. No specialty items, no organic, no premium brands. Just the basics you buy every week.

Prices may vary by canton and promotional week. For branded products like Nutella, Barilla or Coca-Cola, bonus.ch found mostly identical prices at Aldi, Coop, Lidl and Migros in August 2025; the largest gap was 30 centimes. Source: 50-product comparison on the Rappn Blog.
What these numbers actually mean
Looking at the table, Migros' M-Budget line sits under Coop's Prix Garantie on seven of the ten staples. On some products the gap is significant. M-Budget butter is 55 centimes cheaper. M-Budget spaghetti costs almost half the price. Milk, calculated per litre, is 12% less.
Across all ten items it almost evens out: CHF 39.13 at Migros, CHF 39.02 at Coop. What it means for you depends on what goes into your basket.
But there's one important exception: chicken. Coop's Prix Garantie chicken breast costs CHF 11.50 per kilo, 17% under M-Budget at roughly CHF 13.80. If meat is a significant part of your budget, that detail matters quite a lot.
Then there's the promotions factor. Both chains change their deals every Thursday, and in a promotion week the picture can flip on individual products, in either direction.
The bottom line: the cheapest supermarket isn't always the same one. It changes every week, depending on what you're buying and which offers are running.
Migros own-brand prices vs other Swiss supermarkets
M-Budget is Migros' entry line and Prix Garantie is Coop's answer to it. On the June 2026 basket, M-Budget is ahead on seven of the ten items: natural yoghurt at CHF 0.80 against roughly CHF 0.90, spaghetti at CHF 1.20 against roughly CHF 1.80, eggs at CHF 3.10 against CHF 3.30. Two items are effectively level, dark bread at CHF 1.00 and coffee beans at CHF 8.50 against CHF 8.90. The one clear exception is chicken breast, where Prix Garantie at CHF 11.50 per kilo sits 17% under M-Budget at roughly CHF 13.80. Own-brand pricing therefore moves item by item, not chain by chain.

Frequently Asked Questions
Is Migros cheaper than Coop?
On most basic products, yes: in our June 2026 table M-Budget is lower than Prix Garantie on seven of ten items. The advantage is strongest on dairy and pasta. However, Coop is lower on budget chicken, and in promotion weeks the picture can shift on individual products. Branded products mostly cost the same at both. In the K-Tipp basket of 100 everyday products (August 2025), Coop came to about 3 percent more than Migros, CHF 250.70 against CHF 243.54.
How much can I save by choosing the right supermarket?
On the 10-staple basket we checked in June 2026, almost nothing: CHF 39.13 at Migros against CHF 39.02 at Coop, because Coop's lower chicken price offsets the lower M-Budget prices. In the K-Tipp basket of 100 everyday products (August 2025), Coop came to about 3 percent more than Migros, and Aldi and Lidl were lower still at CHF 230.94 and CHF 232.83. The trick isn't being loyal to a supermarket. It's being loyal to your wallet.
Is there an app to compare Swiss supermarket prices?
Yes. Rappn is a free, neutral app that compares grocery prices across Swiss chains, with no commercial agreements with any retailer and no account needed. It covers Migros, Coop, Aldi, Lidl, Denner, Aligro and Otto's, in all 26 cantons, in English, German, French and Italian.
Coop or Migros: which is lower on the weekly shop?
On the 10 staples we checked in June 2026, it is almost level: CHF 39.13 at Migros against CHF 39.02 at Coop. M-Budget is lower on seven of the ten, and the gap is widest on dairy and pasta. Coop turns it around on budget chicken breast at CHF 11.50 per kilo, and promotion weeks can shift individual products either way. Which chain is lower for your basket depends on what is on offer that week.
How do Coop and Migros prices compare on branded products?
They barely differ. In August 2025 bonus.ch found branded goods such as Nutella, Barilla and Coca-Cola mostly at the same price at Aldi, Coop, Lidl and Migros, with a largest gap of 30 centimes. The own-brand lines are where the differences sit: M-Budget against Prix Garantie, item by item, as the June 2026 table shows.
