If you're searching for "the cheapest supermarket in Switzerland", you're asking the wrong question.
No supermarket is cheapest on everything. Lidl had the lowest total basket in the K-Tipp and RTS tests, but doesn't stock the same Emmentaler you'll find at Migros. Migros has M-Budget at near-discount prices, but doesn't sell alcohol. Coop is the most expensive on basics, but has the lowest budget chicken price in this comparison. Denner is a discounter that costs more than Migros in tests. Aldi has prices identical to Lidl but is closing stores.
The right question is: where should you buy what?
This guide breaks down the weekly shop category by category and shows where each one came out lower in this comparison.

Dairy: M-Budget and the Other Budget Lines
| Product | Migros | Coop | Aldi | Lidl | Denner |
|---|---|---|---|---|---|
| Whole milk /L | CHF 1.03 (M-Budget) | CHF 1.17 (Prix Garantie) | ~CHF 1.10 | ~CHF 1.10 | ~CHF 1.15 |

| Branded butter (Die Butter) | CHF 3.95 | CHF 3.95 | CHF 3.95 | CHF 3.95 | CHF 3.95 |
Last row matters: branded products cost the same everywhere. Only the budget line makes a difference.
Meat: where Prix Garantie sits
Coop Prix Garantie chicken breast at CHF 11.50/kg is the lowest price in this five-chain comparison, checked in September 2026, below Aldi and Lidl. Prix Garantie cut meat prices by up to 27% in 2025. For promoted meat, Migros and Coop feature different cuts from week to week.
Fruit and Vegetables: Migros Cut Prices
The Tiefpreis programme in 2025 made fruit and veg 3.6% cheaper on average at Migros. Carrots, potatoes and bananas are at guaranteed lowest prices. Aldi and Lidl have similar or slightly lower prices but a smaller range.
From RTS: the closer to the border (France, Germany, Italy), the more budget products you'll find on the shelves. Supermarkets stock more M-Budget and Prix Garantie where cross-border shopping is a threat.
Household: Only Buy on Promotion
Detergent, toilet paper, soap: these products don't expire and go on promotion regularly. Buying at full price is the most expensive mistake you can make.
Coop and Migros both put detergent on promotion several times a year, in different weeks. Rule: never buy detergent at full price. Wait for the promotion, buy 2–3 packs, done.
Coffee and Wine: Who Sells What
Coffee promotions at Denner come round regularly. Coop sells alcohol in-store with a full range. Migros doesn't sell alcohol in-store.
Branded Products: Same Price Everywhere
bonus.ch confirmed it in August 2025 with 20 branded products: Nutella, Barilla, Coca-Cola cost virtually the same everywhere; the largest gap was 30 centimes, or 4.5% (San Pellegrino). If your basket is mainly branded products, the store you choose barely matters.
Specialty Products: Watch Out at the Big Chains
K-Tipp tested 30 uncommon products (sweet potatoes, rocket, herb butter, cinnamon): Lidl CHF 53.87, Migros CHF 85.37 (+58%), Coop CHF 87.22 (+62%). Sweet potatoes: CHF 1.29/kg at Lidl vs CHF 8.90/kg at Migros/Coop.
For products you don't buy every day, the discounter is often dramatically cheaper.
The Expert's Weekly Plan
Wednesday evening (10 min): check the coming week's deals. Migros, Coop and Denner start on Thursday; the Migros and Denner flyers are out on Wednesday.
Weekly shop (nearest store): basics with the budget line. Milk, bread, eggs, pasta, veg. Almost no price difference between stores.
Targeted shop (when it's worth it): detergent, coffee or meat on promotion? Stock up.
Once a month (optional): Aldi/Lidl for specialty products, spices, cleaning supplies.
What that adds up to depends on your basket and on the week, so we put no monthly figure on it. For scale: in the K-Tipp basket of 100 everyday products (August 2025), Coop came out about 8.6 per cent above Aldi.
