If you shop at Migros or Coop — and roughly seven in ten Swiss households do — you've stood in front of these two private labels at some point: M-Budget, the white-and-orange line that Migros launched back in 1996, and Prix Garantie, the red-on-white line that Coop introduced in 2005 to fight back against discounters like Aldi and Lidl.
Both promise the same thing: the lowest possible price within their parent retailer, on the everyday products you buy without thinking. The question that almost nobody asks aloud — which one is actually cheaper, and on what? — has a more interesting answer than you might expect.
This is a category-by-category breakdown. No paid endorsements, no affiliate links. Just the patterns we see across thousands of weekly shopping baskets.
The setup: two giants, two strategies
M-Budget and Prix Garantie are both designed to shadow discounter pricing, but they got there from different directions.
M-Budget came first and is deliberately a brand: white-and-orange packaging, recognizable typography, even a Migros credit card with the same name. Migros uses it as a price floor across roughly 600 SKUs spanning food, household, drinks, and even mobile services. The product range is broad and confident.
Prix Garantie was a direct response. Coop launched it the year discounters started taking real market share, and the name itself is the value proposition: guaranteed price, lowest in store, no exceptions. The line covers around 500 SKUs and is positioned more functionally — same purpose, less personality.
Both lines occupy the bottom shelves (literally — that's where they sit physically in most stores) and both are routinely benchmarked against Aldi and Lidl by Swiss consumer organizations like K-Tipp and Comparis.
Category by category
The honest takeaway, before the table: the per-unit prices are usually within a few centimes of each other. When one is meaningfully cheaper, the difference shows up in package size and unit pricing, not in shelf price. Always check CHF per kilo or per litre, not the front-label price.
| Category | Where the win sits | What to watch |
|---|---|---|
| Dairy basicsM-Budget | UHT milk and natural yoghurt typically come in slightly larger pack sizes at Migros, dropping the per-litre cost. | The 1 L vs 1.5 L bottle on milk is the classic gotcha. Compare per litre, not per bottle. |
| Bread & bakeryPrix Garantie | Coop's house bakery scale gives Prix Garantie a narrow edge on standard sliced loaves and toast. | Migros's own-bakery non-budget breads are often closer in quality but priced higher. |
| Pasta & riceM-Budget | 500 g pasta and long-grain rice are consistently a few centimes cheaper at Migros, especially in bulk-friendly sizes. | Aldi and Lidl beat both lines on dry goods. Worth a separate stop if you go through volume. |
| Eggs (10-pack) | Effectively a draw. Both track each other within a few centimes per box. | Watch the Aktion rotation — promotional pricing on eggs swings far more than the gap between the two budget lines. |
| Coffee (ground)Prix Garantie | Standard 500 g ground coffee tends to come in a bit cheaper at Coop's budget line. | Quality is comparable but not identical. If coffee matters to you, the budget tier is rarely the right call regardless of who wins. |
| Tinned tomatoesPrix Garantie | Coop's tomato pulp and chopped tomatoes have held a slight per-can edge across recent years. | If you cook pasta sauce weekly, this category alone can move the needle. |
| Frozen vegetablesM-Budget | 1 kg bags of mixed frozen veg, peas, and spinach typically price out cheaper per kilo at Migros. | Aldi and Lidl beat both, but if Migros is your only stop, the budget line is the move. |
| Meat staples | This is the most volatile category. Whichever store has chicken breast or ground beef on Aktion that week wins decisively. | Don't anchor your shop here. Plan around this week's promotions, not the budget label. |
| Cleaning & householdPrix Garantie | Detergents, dish soap, basic toilet paper — Prix Garantie tends to win on per-unit pricing. | The Migros equivalents are similar in quality but slightly higher. Aldi often beats both. |
| Snacks & biscuitsM-Budget | Crackers, plain biscuits, savory snacks edge cheaper at Migros, especially in larger packs. | Easy place to overspend regardless of brand. The budget line is only a saving if you'd buy snacks anyway. |
The actual rule: Across a typical 50-item weekly basket, the cumulative difference between an all-M-Budget basket and an all-Prix Garantie basket is usually under CHF 5. The store you pick matters far less than whether you reach for the budget line at all — choosing budget over name-brand within the same store typically saves 20–35% on the same item.
Three gotchas almost everyone misses
1. Pack-size sleight of hand
The single most common mistake when comparing these lines is reading the front-of-pack price instead of the unit price. A 750 g M-Budget pasta and a 1 kg Prix Garantie pasta can sit side by side at near-identical shelf prices and look interchangeable. The per-kilo math tells a different story.
Both Migros and Coop are required to display unit pricing — CHF per kilo or per litre — somewhere on the price label. It is usually small. Train your eye to it.
2. The "budget tier inside the budget tier"
Both lines occasionally split into sub-tiers. Migros has lower-tier seasonal items priced under M-Budget. Coop has tactical Aktion promotions that temporarily price brand-name products below Prix Garantie equivalents. The cheapest item is not always the one with the budget label on it.
3. Quality-equivalent, not quality-identical
Both lines source from third-party suppliers, and the suppliers can change. A product you've bought for two years can quietly shift recipe, source, or pack size. If a Prix Garantie or M-Budget item suddenly tastes different, you are not imagining it — and the cheaper option may not stay the cheaper option once a substitution happens. Trust nothing on autopilot for more than one shopping cycle.
How they stack up against Aldi and Lidl
The honest framing: across a basket of staples, Aldi and Lidl typically beat both M-Budget and Prix Garantie by roughly 10–20%, sometimes more on dry goods, household, and own-brand dairy. That is the whole reason these two private lines exist — to keep Coop and Migros from losing customers entirely on price.
So why ever buy M-Budget or Prix Garantie at all?
- Convenience: if you're already in Coop or Migros for fresh produce, hot food, or a specific brand, a budget-line top-up beats a dedicated trip to a discounter.
- Loyalty programs: Cumulus and Supercard accumulate on these purchases. Discounters' own programs (Lidl Plus) are improving but still narrower.
- Product range: if you need a specific item that isn't carried at Aldi or Lidl, the budget tier in the bigger store keeps the cost reasonable.
For a household that wants to actively minimize the grocery bill, the typical winning pattern from our beta is Migros or Coop as the main store, plus one discounter for staples. Picking only the budget line at Migros or Coop, and never going to a discounter at all, leaves real savings on the table.
The verdict
If you have to pick one and never deviate: the two are close enough that geography wins. Whichever of the two has the closer, more convenient store should be your default. The cumulative basket difference is too small to be worth a longer trip.
If you can split: bias toward Prix Garantie for cleaning, household, coffee and bread; bias toward M-Budget for pasta, frozen veg, dairy and snacks. The total weekly difference will rarely exceed CHF 5–8, but over a year that is real money — and it costs you nothing extra in time.
If you genuinely want to minimize the bill: stop comparing M-Budget and Prix Garantie to each other. Compare both to Aldi, Lidl, and this week's Aktion rotation across all six major chains. The savings ceiling lives there, not in the budget-line standoff.
