Coop vs Denner: which is cheaper for your weekly basket?

Coop and Denner are not really the same kind of shop, which is why "which is cheaper" has no single answer. Coop is a full-range supermarket: a huge assortment, fresh counters, branded goods, the Prix Garantie budget line, Naturaplan organic and the Supercard. Denner is a discounter: smaller stores, a focused range of branded staples, a strong wine, coffee and spirits selection, its own Denner-brand products and aggressive weekly Aktionen. Denner tends to win on a tight basket of branded staples and on wine and coffee, while Coop tends to win when you want range, fresh, organic and one-stop convenience, and on promotion weeks. The smart move is to match the shop to the basket and check this week's real prices before you go.

Sources checked May 2026: Swiss consumer-test publications K-Tipp and Kassensturz (SRF) for blind product and own-brand tests; Beobachter and Bon a Savoir / FRC for price journalism; the Federal Statistical Office (BFS / OFS) for general price-level context; the retailers' own published information (Coop Prix Garantie, Naturaplan, Supercard; Denner's discounter format and weekly Aktionen). Denner is majority-owned by the Migros group. Specific prices and promotions change every week, so this guide explains how to judge the two rather than quoting figures that go stale; check live prices in the Rappn app.

Coop vs Denner: two different jobs, not one race

Before comparing prices it helps to see what each shop is built to do. Coop is one of the two big full-range supermarkets in Switzerland. Its strength is breadth: tens of thousands of products under one roof, a real fresh, meat, fish and cheese offer, a wide branded selection, the Prix Garantie budget line for everyday staples, the Naturaplan organic range and the Supercard loyalty programme. You can do an entire household shop at Coop without a second stop.

Denner is a discounter, and a long-established one. Its strength is a focused, fast-moving range of roughly everyday branded staples at sharp prices, plus its own Denner-brand products, in smaller stores that are quicker to walk. Denner is also one of the largest wine sellers in the country and is known for coffee and spirits, with weekly Aktionen that can be very aggressive. One detail many shoppers do not realise: Denner is majority-owned by the Migros group, so it sits inside the same family as Migros rather than being an independent third force. That shared ownership is also why its promotion calendar now lines up with the big chains.

Who wins which category

Here is a neutral, category-by-category map. Neither chain wins everything, and a strong Aktion can flip any single line in any given week.

Where Denner is the better pick

If your trip is a short, focused one (some branded staples, a couple of bottles of wine, coffee, a few drinks and snacks) Denner is often the more efficient and cheaper choice. The stores are smaller and faster, the everyday branded items are keenly priced, and the wine and spirits offer is genuinely strong. The trade-off is range: you will not always find the specific brand, size, fresh item or organic line you wanted, because the assortment is deliberately narrow. For a top-up shop rather than the big weekly one, that narrowness is a feature, not a bug.

Where Coop is the better pick

If you are doing the full weekly shop for a household, Coop's breadth usually wins on convenience and often on the total bill once you count the trips you avoid. You get fresh produce, a meat and fish counter, a wide cheese and bakery offer, branded and budget lines side by side, and the broadest organic range in Naturaplan. Coop's Prix Garantie line keeps everyday staples close to discounter level, and Swiss consumer tests by K-Tipp and Kassensturz repeatedly find that budget and own-brand lines often match name brands in blind tests, so trading down inside Coop is frequently a free saving. Add the Supercard, and a loyal Coop shopper collects points and vouchers across the year. For the head-to-head against the other giant, see our Migros vs Coop prices guide.

The catch: it depends on the week and the basket

Here is the honest complication. Because both chains run different promotions every week, the cheaper shop for your specific basket is rarely the same two weeks running. Since 5 February 2026, Migros, Coop and Denner share the same promotion cycle, Thursday to Wednesday, so their offers refresh together and a winning line at one can be matched at the next refresh. A static article cannot tell you who is cheaper for your trolley today. Only live prices can. If your goal is simply the lowest total bill across all chains, our cheapest supermarket in Switzerland guide widens the field beyond these two, and best value supermarket weighs price against quality.

This is exactly the gap Rappn fills. You search a product, for example coffee, and see every active offer across Coop, Denner, Migros, Aldi, Lidl, Otto's and Aligro at once, with the price, the discount and the store. The unit price (per kilo or litre) sits next to the shelf price, the only honest way to compare two pack sizes. Everything is filtered to your canton, and you can set an alert so you are told the moment a product you buy regularly drops in price. It is free, and it has no commercial deal with any retailer.

So is Coop or Denner cheaper?

The neutral answer: it depends on the basket. For a focused run of branded staples, wine and coffee, Denner is frequently cheaper and faster. For a full household shop with fresh, organic and range, Coop is usually the better overall pick, and its Prix Garantie line keeps the budget items competitive. Neither is "always cheapest", and the only way to know who wins your basket this week is to compare the live offers side by side. That is the whole reason Rappn exists.
