Lidl vs Aldi in Switzerland: Which is Actually Cheaper?

Updated: September 2026. Sources: K-Tipp, RTS A Bon Entendeur, Kassensturz.

Lidl and Aldi arrived in Switzerland in the early 2000s with a straightforward pitch: fewer products, no frills, lower prices. They've been reshaping Swiss grocery shopping ever since. Migros and Coop had to create their M-Budget and Prix Garantie budget lines specifically to compete with them on price.

But between the two discounters, which one is actually cheaper?

The short answer is that they're extremely close. The price gap between Lidl and Aldi is tiny compared to the gap between either discounter and Migros or Coop. That said, there are meaningful differences beyond price: Lidl's loyalty card, store locations, product range and weekly promotions all play a role.

The data here comes from independent tests by K-Tipp and RTS "A Bon Entendeur", plus the promotions we track continuously through Rappn.

Is Aldi or Lidl cheaper in Switzerland?

On the shelf price the two are almost level. In the K-Tipp basket of 40 everyday products, Lidl came to CHF 66.64 and Aldi to CHF 66.69, five centimes apart on the whole shop. In the RTS basket of 30 basic products, Lidl was CHF 162.05 and Aldi CHF 166.59, a gap of about CHF 4.50 or 3%. In the RTS basket (April 2024), Migros and Coop came to about 1 to 5 percent more. What separates them is everything around the price: Lidl Plus coupons and the in-store bakery on one side, a denser store network and no card at all on the other.

The numbers

Let's start with the facts. In two independent tests conducted on the same day, using the same shopping list in comparable stores, Lidl and Aldi came out virtually tied:

K-Tipp test (40 everyday products):

• Lidl: CHF 66.64
• Aldi: CHF 66.69
• Difference: 5 centimes on the entire basket

RTS "A Bon Entendeur" test (30 basic products):

• Lidl: CHF 162.05
• Aldi: CHF 166.59
• Difference: about CHF 4.50, roughly 3%

For context: in the same RTS test (April 2024), Migros came in at CHF 170.37 and Coop at CHF 167.82, about 1 to 5 percent more than the two discounters.

In the more specialised K-Tipp test (less common items like cauliflower, rocket, herb butter, Ticino bread), the gap between discounters and big supermarkets widened further: the Lidl basket cost CHF 53.87, the Migros basket CHF 85.37. Nearly 60% more.

Tests compare the cheapest available product in each store. Prices vary by canton and week.

What Lidl offers

Lidl Plus: the card Aldi doesn't have. This is arguably the biggest practical difference between the two. Lidl Plus is a free app that works as a digital loyalty card. Scan it at the checkout to get automatic discounts on selected products, personalised coupons and points (one point per franc spent) that you can exchange for vouchers or free products. Aldi has no loyalty programme at all. Their approach is "low prices every day, for everyone, no card needed."

In practice, Lidl Plus adds app discounts and coupons on selected products on top of the shelf price, so the benefit grows with how often you shop at Lidl.

The lowest total in the RTS basket. In the RTS "A Bon Entendeur" basket of 30 basics (17 April 2024), Lidl came out lowest of five Swiss supermarkets. In March 2026, Lidl Switzerland also permanently lowered prices on around 60 everyday items.

The bakery. Anyone who shops at Lidl regularly knows the in-store bakery: the Ruchbrot, the butter croissants, the milk rolls. For many families, it's a genuine selling point.

What Aldi offers

More stores across Switzerland. Aldi Suisse has a wider network of locations. Outside the major cities, you're more likely to find an Aldi nearby than a Lidl. If convenience matters, Aldi often has the shorter drive.

The everyday-low-price philosophy. Aldi doesn't rely on big flash promotions. Their strategy is consistently low prices without the need to check flyers or activate coupons. If you don't want to think about weekly deals, Aldi is the simpler option.

Growing organic range. Aldi Suisse's own organic label "retour aux sources" has expanded significantly in recent years. Organic milk costs CHF 1.80 per litre at Aldi, the same as Lidl and less than Migros (CHF 1.85) or Coop (CHF 1.90).

What they have in common

Both Lidl and Aldi sell alcohol (wine, beer, prosecco) directly in store. This sets them apart from Migros, which doesn't sell alcohol in its supermarkets. If you want to do your entire shop in one place, drinks included, both discounters have you covered.

The main limitation for both is the product range. Lidl and Aldi carry around 1,500–2,000 products per store, compared to 20,000–30,000 at a mid-sized Migros or Coop. If you're looking for a specific ingredient, a Swiss regional product or a particular brand, you may not find it at the discounter.

Both have significantly expanded their fresh fruit and vegetable offering in recent years, and quality has improved noticeably. Several tests, including by Kassensturz, have confirmed that fresh produce quality at the discounters is now comparable to the big supermarkets.

So, Lidl or Aldi?

If you have both nearby, the choice comes down to your habits more than the prices.

Choose Lidl if you want to take advantage of the coupons and extra discounts from Lidl Plus, you appreciate the fresh in-store bakery, and you don't mind checking the weekly promotions for deals.

Choose Aldi if you prefer a straightforward shop with low prices every day and no need for apps or loyalty cards, if your nearest Aldi is more convenient, or if you're looking for a good organic range.

Either way, the test baskets came in below Migros and Coop: in the K-Tipp basket of 100 everyday products (August 2025), Migros and Coop cost about 5 to 9 percent more than Aldi and Lidl, in the RTS basket (April 2024) about 1 to 5 percent more. What that means for your weekly shop depends on your basket.

The insider tip? The biggest savings don't come from choosing between Lidl and Aldi. They come from buying your staples at the discounter and picking up branded products at Migros and Coop only when they're on promotion. That's the combination that really pays off.

Compare deals from every supermarket

Checking flyers from every supermarket each week isn't realistic for anyone.

Rappn collects the promotions of Migros, Coop, Aldi, Lidl, Denner, Otto's and Aligro in one place. You can filter by canton, search for the products you care about and see which chains have them on promotion this week.

If there's a product you buy regularly, you can set up an alert and get notified when it goes on promotion.

Rappn is free, ad-free and has no commercial agreements with any retailer.
