Mineral Water Deals in Switzerland: Evian, Valser and Eptinger

Evian deals: which chains can actually run them?

The answer starts with the assortment. Evian is listed, among others, in the online shops of Migros, Coop and Denner (migros.ch, coop.ch, denner.ch, checked August 2026), and all three start their weekly deals on Thursday.

So on a Thursday, looking for Evian means watching several flyers, or running one search that covers every chain, like the list at the top of this page. Because Evian is imported, it belongs to the share of the market that in 2025 accounted for 474.3 million of a total 993.6 million litres, per the SMS association: just under half of Swiss mineral water consumption.

Valser water deals: where Valser sits on the shelf

Valser is listed at all three big full-range chains: Valser Classic on migros.ch, Valser products on coop.ch and Valser Mineralwasser prickelnd on denner.ch (checked August 2026). As with Evian, a deal can come from several chains, and the big three of them start on Thursday.

Valser differs from Evian in origin, not in how it is promoted. As a branded water it is discounted in the same shelf category: almost always as a six-pack, or as a combination of several six-packs, rarely as a single bottle.

Eptinger deals at Aldi: why there in particular?

"Eptinger Aktion Aldi" is a search with a concrete reason behind it: Eptinger is a branded water that Aldi Suisse stocks too. On aldi-suisse.ch, Eptinger Mineralwasser is listed as a six-pack of 1.5-litre bottles, and the brand appears in promotion rounds filed under "from Thursday". Coop additionally lists Eptinger as 6 × 150 cl, and Denner carries Eptinger still and sparkling (coop.ch, denner.ch).

With Eptinger, comparing a discounter against a full-range chain genuinely works, because the same product exists in both channels. Those overlaps are the only place a brand-level comparison is clean: with own labels you are necessarily comparing different products.

Aproz and Henniez: the Swiss line

Aproz is not a bought-in brand: it belongs to Migros Industrie. Per migrosindustrie.ch, Aproz Sources Minérales SA has been bottling water from the Rhone valley in Valais since 1947, fills over 170 million litres a year, and runs five filling lines with a capacity of up to 100,000 bottles per hour. You will therefore find Aproz at Migros.

Henniez, by contrast, is a classic branded water listed at Migros and Coop, still and sparkling (migros.ch, coop.ch, August 2026). San Pellegrino is likewise listed at Migros and Coop, but it sits in a different price bracket from the standard Swiss waters, because it sells mostly in smaller formats, which structurally pushes the per-litre price up.

Water deals this week: why the price per litre decides

Water is the category where the shelf price misleads most, because pack formats vary so much: 6 × 1.5 litres, 6 × 1 litre, 6 × 75 cl, 24 × 50 cl. A cheaper pack can simply hold less water. That is why federal rules require a unit price for measurable goods: for measurable goods whose retail price depends on the quantity sold, the base price per litre, kilogram, metre and so on must be shown (kmu.admin.ch, "Kennzeichnung der Preise"). The francs-per-litre figure is already on the shelf label, just printed smaller than the deal price.

Then there are the crossed-out prices. Since 1 January 2025, a comparison price may be shown next to the price actually payable only if the goods were offered at that price for at least 30 days beforehand (Art. 16 para. 1 PBV, via kmu.admin.ch). A "was" price is therefore a price that really existed, but it says nothing about what the same volume of water costs this week at another chain.

Is there a deposit on PET bottles in Switzerland?

No. There is no deposit on PET drinks bottles in Switzerland; collection is financed through the advance recycling fee levied by PET-Recycling Schweiz and included in the sale price. According to the BAFU, consumers return over 80 percent of the PET drinks bottles put into circulation; the Beverage Packaging Ordinance requires a rate of at least 75 percent, failing which the federal government could introduce a deposit. Our guide to bottle deposits and recycling in Switzerland covers the whole system.

On a discounted six-pack there is nothing to get back later: the deal price is the final price. Some reusable glass containers are different, they do carry a deposit.

Which chain has the cheapest water this week? It depends

It depends on the brand, the pack format and your canton. In the same week one chain can lead on the Evian six-pack and trail on still own-brand water, and assortments differ by region. That is why there is no price table here: every figure would be wrong by the following Thursday. This week's prices are in the list at the top of this page, by canton.

Rappn pulls together the current deals from seven chains, namely Migros, Coop, Aldi Suisse, Lidl, Denner, Aligro and Otto's, in four languages and filterable by canton. The comparison shows the unit price per litre next to the pack price, which for water is the figure that actually matters, and you can set a price-drop alert on your brand instead of opening five flyers every Thursday. If you want to know what water costs outside deal weeks, our guide to bottled water prices in Switzerland goes deeper; for the whole-basket picture, see the comparison of Swiss supermarkets.

Next step: open the current offers, search for "water" and filter to your canton. Then set a price alert on the brand you drink anyway: Rappn tells you on Thursday instead of you having to look. Rappn is free and is paid by no retailer.
