Guide
Diapers are the textbook stock-up category: predictable consumption, long shelf life, and brand-range discounts that have come back again and again at the big chains. Since February 2026 the promo weeks at Migros, Coop and Denner start on Thursday, with Aldi adding a Monday round. See the current diaper offers live and neutrally compared in the Rappn app.
Diapers are the textbook stock-up category: consumption is predictable, the product keeps for a long time, and discounts on the Pampers range have come back again and again at the big Swiss chains in recent years. Compare the unit price per diaper, buy during promotions instead of ad hoc, and the yearly bill drops noticeably.
Sources checked regularly: corporate.migros.ch (promo start moved to Thursday, February 2026), Coop press release via foodaktuell.ch (January 2025), aldi-suisse.ch, lidl.ch, denner.ch, coop.ch. Price examples are regular shelf prices, verified May 2026 in the Rappn baby guide. This week's diaper deals are live in the Rappn app.

Why diapers are the perfect promotion category
Few product groups are as predictable as diapers. A baby needs roughly 6 to 10 diapers per day in the first year; at an average of 7 that adds up to about 2'550 diapers in twelve months. At the same time diapers do not spoil, need no cooling and store easily. That is exactly why the category is made for a stock-up strategy: do not buy when the pack runs out, buy when the price is right.
The strategy has one limit: sizing. Babies grow faster than you expect, and a tower of size 3 is useless once your child has moved to size 4. As a rule of thumb, one promotion purchase should cover a few weeks of need, not months. That keeps the risk of being stuck with the wrong size small.

How the Swiss promo rhythms work
| Chain | New promotions | Relevant for diapers |
|---|---|---|
| Migros | Thursday to Wednesday (since 5 February 2026) | Discounts on branded diapers possible; own brands Milette and M-Budget |
| Coop | Thursday to Wednesday (since January 2025) | Dedicated nappy promotions section on coop.ch; own brand Prix Garantie baby nappies |
| Denner | Thursday to Wednesday | Denner Woche flyer on Wednesday, one day before the start |
| Aldi Suisse | Monday and Thursday | Pampers and Mamia (as of September 2026) |
| Lidl | Thursday, second wave on Monday, Super Weekend Thursday to Saturday | Own brand Lupilu permanently in the range |
Waiting can pay, because discounts on entire brand ranges keep coming back. There is never a guarantee that a diaper promotion runs this particular week, though. That is exactly why a price alert beats checking the Migros and Coop flyers every day.
Unit price per diaper: the only fair comparison
Pack prices are almost meaningless for diapers because pack counts vary wildly: 24-piece carry pack, 46-pack, 108-piece box. Things only become comparable with the unit price, in Swiss shops called the Grundpreis: pack price divided by piece count. Online shops often show the per-piece price next to the product; in store you do the quick division yourself.
Reference, May 2026: price per diaper
| Example | Calculation | Price per diaper |
|---|---|---|
| Pampers Baby Dry size 4, 46 pieces, CHF 18.90 | 18.90 ÷ 46 | approx. 41 rappen |
| Same pack with a 30% discount | 13.25 ÷ 46 | approx. 29 rappen |
| Same pack with a 50% discount | 9.45 ÷ 46 | approx. 21 rappen |
| Pampers half-month box, 108 pieces | CHF 38 to 42 | approx. 36 to 39 rappen |
| Milette size 4 (Migros own brand), regular | depends on pack | approx. 19 to 24 rappen |
| Lidl Lupilu size 4, regular | depends on pack | approx. 15 to 20 rappen |
Regular shelf prices, verified May 2026 (Rappn baby guide). The discount rows are worked examples, not current offers.
The table shows two things. First, only a strong promotion brings the brand into own-brand price territory. Second, Milette, Prix Garantie or Lupilu already sit at regular price roughly where Pampers only arrives with a deep discount. If you stay with the brand, you save through timing; if you switch to the own brand, you save every week. Over a full diaper year, the gap between the most expensive and the cheapest route quickly reaches the order of CHF 600. For detailed price levels and brand comparisons, see the guide baby food, formula and diaper prices in Switzerland.
The stock-up strategy: track promotions instead of buying ad hoc
Whoever buys only when the last diaper is gone pays whatever the shelf happens to say that day. The planned alternative looks like this:
- Set a unit-price anchor: memorise the regular per-diaper price of your brand in your size. Only then can you tell instantly whether a promotion is genuinely good.
- Alert instead of flyer: set a Rappn price alert for your brand and size. The app pings you when the diaper goes on promotion at one of the 7 chains.
- Cover a few weeks per promotion: watch for minimum quantities, some promotions only apply when you buy several packs.
- Plan for size changes: if a size change is close, buy the next size up instead of hoarding the old one.
Thursday is the main day to check, Monday the second because of Aldi and Lidl. With an alert set, you do not even need to remember that.

Frequently Asked Questions
When do diapers go on promotion in Switzerland?
There is no fixed diaper calendar, but the promo weeks at Migros, Coop and Denner start on Thursday, and Aldi Suisse launches new offers on Monday and Thursday. A Rappn price alert notifies you of the next one automatically.
How much can you save with diaper deals?
It depends on how deep the discount is. A worked example: on a 46-pack at CHF 18.90, a 30 percent discount cuts the unit price from about 41 to 29 rappen. Across roughly 2'550 diapers in year one, that quickly adds up to a three-digit amount.
Is Pampers on promotion cheaper than Milette or Lupilu?
Not automatically. Milette costs about 19 to 24 rappen per diaper at regular price and Lupilu about 15 to 20 rappen (as of May 2026). Pampers Baby Dry in the small pack sits around 41 rappen at regular price and only reaches own-brand territory with a discount of roughly 50 percent. Always recalculate the unit price.
How many packs should I buy during a promotion?
As a rule of thumb, a few weeks of need, not months. Babies change sizes faster than expected, and a big stock in the wrong size is wasted money. Also watch minimum quantities: some promotions only apply when you buy several packs.
How do I calculate the price per diaper?
Pack price divided by piece count. Example: CHF 18.90 for 46 diapers is about 41 rappen per diaper. Only this unit price makes 24-packs, 46-packs and 108-piece boxes comparable. Online shops often show the per-piece price right next to the product.
Where do I see the current diaper deals?
In the Rappn app you see the diaper offers of all 7 chains live in one place, searchable by product and filterable by category, price and canton. With a price alert on your brand and size, you no longer need to search at all.
