A supermarket app that many shoppers only flash at the till is quietly turning into a serious weapon against rising prices.
Across France, households wrestling with food inflation are finding small but regular savings in an unlikely place: the Intermarché mobile app. What began as a simple digital loyalty card has grown into a tightly packed toolbox of promotions, personalised discounts and game-like challenges that can trim grocery bills week after week.
From paper leaflets to preview deals on your phone
Anyone used to grabbing a paper leaflet at the supermarket entrance will recognise the weekly ritual: standing in an aisle, flicking through pages to find the best bargains. The Intermarché app moves that planning stage back home, before you even reach the store.
Inside the app, all weekly catalogues are digitised and usually appear several days ahead of the new promotion period. That early access changes the way people plan their food shop.
By browsing the upcoming catalogue on your sofa, you can map out meals, compare offers and build a list before prices hit the shelves.
This simple shift helps prevent rushed, impulse purchases driven by end-of-aisle displays. Instead, families can target the best percentage discounts – sometimes around a third off – while checking what they already have at home.
Why early access matters for stretched budgets
Seeing promotions in advance sounds minor, but it can unlock more strategic shopping habits. With the app open and a notebook – or notes app – in hand, households can:
- Plan a week of dinners around the strongest discounts
- Stock up on non-perishables when they hit a low price
- Avoid buying full-price alternatives in a rush
- Spread bulk purchases across several weeks to smooth cash flow
For many French families, this is less about chasing every single bargain and more about putting some order back into a budget that has been under real pressure.
At least 20% back with weekly e‑coupons
The real engine of savings in the Intermarché app is found in the digital loyalty space. Once a shopper registers their physical Intermarché card inside the app, a different type of promotion appears.
Each week, users can activate an e‑coupon that gives at least 20% back on their loyalty card on all products from a single aisle. The exact aisle changes, but the principle is clear: choose the right category, and a chunk of what you spend comes back as a credit.

That minimum 20% “advantage carte” turns the loyalty account into a kind of mini savings pot that grows with carefully planned baskets.
Alongside that weekly e‑coupon, the app shows personalised promotions such as “2+1 free” on selected brands. These are tailored to what customers tend to buy, nudging them towards multi-buy deals that top up the loyalty balance.
Where to find the most profitable offers
All these benefits sit behind a clearly labelled section of the app. On the home screen, the “Mes Avantages” section acts as a hub:
| Section | What you get |
|---|---|
| E‑coupons | Weekly aisle-wide discounts paid back onto the loyalty card |
| Offres de la semaine | Current promotions and personalised multi-buy deals |
| Mes Défis Gagnants | Challenge-based rewards that build up monthly |
Crucially, these offers are not automatically applied. Shoppers need to tap and activate them before heading to the checkout. It adds one more step to the routine, but missing it means leaving money on the table.
“Winning challenges”: gamifying up to €50 a month in savings
One of the more unusual features, particularly for a supermarket app, is the system of “défis gagnants”, or “winning challenges”. It blends loyalty points with a structure familiar from video games.
At the start of each month, users can pick several challenges to complete. Each one is broken into three levels – bronze, silver and gold – tied to minimum spending thresholds on certain categories or brands.
The further you progress through bronze, silver and gold levels, the more credit you earn on your loyalty card, with the app promising the potential to build up at least €50 per month.
Every time a shopper scans their loyalty card at the till, the app updates their progress. Purchases quietly push them towards the next level, and each step reached unlocks an extra amount of “avantage carte” credited to their account.
A playful nudge towards regular savings
This challenge-based format serves several functions. It encourages users to:
- Stick with one supermarket rather than jumping between chains
- Structure monthly shopping around reaching set goals
- Track returns from their spending in a more visual way
From a consumer angle, the key is to check that a chosen challenge aligns with actual needs. Chasing a gold level on products rarely used at home can quickly backfire, even with loyalty credits attached.
Year-round prize draws: more than just coupons
The Intermarché app also leans on a more traditional tactic: competitions. Throughout the year, it hosts prize draws and instant-win games accessible through the same “Mes Avantages” section.
The rewards are not limited to small vouchers. Users can win full trolleys of groceries, domestic appliances, leisure activities or family trips. Participation rules and dates sit inside the app, giving regular shoppers an extra reason to open it even between food shops.
For loyal customers already using the app for discounts, these games turn routine spending into the occasional opportunity for a sizeable windfall.
While such contests should never be the primary reason to shop, they add a layer of excitement for households that rarely associate grocery runs with pleasant surprises.
How these savings stack up over a typical month
To understand the potential, imagine a family spending €500 a month on groceries at Intermarché. By combining features inside the app, they might manage something like this:
- €15 saved using weekly catalogue promotions on basics like pasta, yoghurt and cleaning products
- €20 in “avantage carte” from carefully selected weekly e‑coupons on key aisles
- €30 credited via winning challenges spread across everyday items
That already amounts to around €65 in value, between immediate price cuts and loyalty credits that can be used on future shops. Those numbers will vary by household, but the structure encourages a mindset where every basket is checked for possible returns.
Reading the fine print: loyalty jargon made simple
The French term “avantage carte” can confuse some shoppers. In practice, it refers to money stored on the loyalty card, not an instant discount at the shelf. That credit can usually be used like cash for future purchases, though some exclusions may apply.
“Cagnottes” or “cagnottés” describe the accumulation of that credit. When the app says up to €50 can be “cagnottés” each month, it means at least that amount could, in theory, be stored on the loyalty card through combined offers and challenges.
Another term worth noting is “2+1 gratuit”. In the app, this generally means that if you buy three units of a product, the value of one is returned to you, either as a direct discount or as loyalty credit, depending on the exact structure of the promotion.
Practical tips to avoid overspending while chasing deals
Every loyalty scheme carries a risk: the temptation to buy more than you need because the offers look attractive. A few simple habits can keep that in check while still using the Intermarché app to cut costs.
- Always start with a list based on real needs, then match it to app offers
- Use weekly e‑coupons mainly on staples you buy anyway, like milk, cereal or toiletries
- Limit challenges to one or two categories per month to stay focused
- Check expiry dates on multi-buys to avoid throwing food away
Handled this way, the app works as a budgeting ally rather than a spending trap. For many shoppers, the biggest gain is not a single spectacular discount but the quiet, repeated reduction in bills that shows up month after month in their loyalty balance and bank account.
