Migros vs Coop: Which is Actually Cheaper?
We compared 10 everyday products using the prices you'll actually find on the shelf. There is a winner, but the full picture is more interesting than you'd expect.
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?
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.
The prices below come from the cheapest own-brand lines: M-Budget at Migros and Prix Garantie at Coop. Checked in April 2026 on migros.ch and coop.ch.

What these numbers actually mean
Looking at the table, the picture is fairly clear: for everyday staples, Migros' M-Budget line is on average 3–5% cheaper than Coop's Prix Garantie. 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.
For a family of 3–4 doing their weekly shop, these differences add up to CHF 30 to 80 per month.
But there's one important exception: chicken. Coop's Prix Garantie chicken breast at CHF 11.50 per kilo is the lowest price for this cut anywhere in Switzerland, cheaper even than Aldi and Lidl. If meat is a significant part of your budget, that detail matters quite a lot.
Then there's the promotions factor. Coop is known for running aggressive promotional weeks, with discounts of up to 50% on detergent, coffee and cheese. During those weeks, Coop becomes cheaper than Migros even in categories where it normally loses.
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.

Frequently Asked Questions
Is Migros cheaper than Coop?
For everyday shopping with basic products, yes. The M-Budget line is on average 3–5% cheaper than Prix Garantie. The advantage is strongest on dairy and pasta. However, Coop wins on budget chicken and often runs more aggressive promotions. For branded products, prices are essentially identical between the two retailers.
How much can I save by choosing the right supermarket?
Between CHF 30 and 80 per month for a family, simply by buying each product wherever it's cheapest. If you add discounters like Aldi, Lidl and Denner to the mix, savings can go up to CHF 200–400 per month. The trick isn't being loyal to a supermarket. It's being loyal to your wallet.
