Is Carrefour More Expensive in Paris? The Same 15 Products Cost 28% More at a Carrefour City Than at a Hypermarché

Yes, if the Carrefour you shop at is a Carrefour City. On November 12, 2026 the same 15 products, matched by barcode, cost €54.56 at the Carrefour City on rue des Pyrénées near Place de la Nation and €42.55 at the Carrefour hypermarket in Montreuil: 28% more, with the median item 26.8% dearer. The Carrefour Market on boulevard de Charonne, also near Nation, charged €42.05, in line with the hypermarket. The gap follows the store format, not the neighbourhood. To check your own store, Scavio's Carrefour API returns the nearby stores for a postal code with POST /api/v1/carrefour/stores, then prices any product at the one you pick with /search or /product and store. Each call is 1 credit, about $0.001 on the Growth plan.

The question comes from a January 2026 r/paris thread with 57 upvotes and 49 comments. The poster found the Carrefour at Nation dearer than Monoprix and asked, in translation, whether Nation "has a local inflation bonus". The top reply ranked Paris grocers by price with Carrefour the cheapest of four, and another noted that a chain's suburban stores can be much cheaper than its Paris ones. Both can be true, and carrefour.fr can show why: it prices each store separately.

What the same products cost near Nation

We searched carrefour.fr through Scavio for eight staples at three stores and at the national online price, one search per staple and place, and kept the 15 products whose EAN appeared at all four. Prices are each store's regular price; promotions are left out.

Three things stand out. Carrefour's own brands are not exempt: Carrefour Classic' milk was €1.47 a litre at the City store and €1.08 at the hypermarket. Only C'est qui le Patron ?! milk cost the same everywhere. And the Market a few streets away priced the basket 1.2% below the hypermarket, so "Carrefour near Nation" can mean very different prices depending on the door you walk through.

The deals differ too. Nutella 400 g carried "Le 2ème à -50%" at the hypermarket and online, but not at the City store, and Carrefour Classic' ground coffee had "Le 2ème à -30%" everywhere except the City store. The range is smaller: "beurre" matched 39 products at the City store, 105 at the hypermarket and 257 online, and the City store listed no fresh eggs online.

Step 1: Find the stores around you

curl -s https://api.scavio.dev/api/v1/carrefour/stores \
  -H "Authorization: Bearer $SCAVIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"lat": 48.8484, "lng": 2.3959, "limit": 20}'

That point is Place de la Nation; a postal_code such as "75012" works too. The 20 nearest stores came back nearest first, mostly Carrefour City and Express, each with banner, format, address and hours. A store carrefour.fr prices online has a store_ref or pickup_refs:

{
  "store_ref": "810130",
  "pickup_refs": [{ "ref": "800338", "name": "Drive Pieton", "type": "pieton", "status": "OPEN" }],
  "name": "City Paris Rue Des Pyrénées",
  "banner": "CARREFOUR CITY",
  "format": "PROXIMITE",
  "address": { "line1": "51 Rue Des Pyrenees", "postal_code": "75020", "city": "Paris" }
}

Only 2 of the 20 had one: this City store and the Carrefour Market at 103 boulevard de Charonne (820024). Adding "service": "drive" returned 20 stores that all had a reference, including the Montreuil (840015) and Bercy hypermarkets.

Step 2: Price the same search at each store

curl -s https://api.scavio.dev/api/v1/carrefour/search \
  -H "Authorization: Bearer $SCAVIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "lait", "store": "810130"}'

The response confirms the scope with "store": "810130" and "price_scope": "store", then up to 30 products with ean, price and unit_price_label. Repeat with "store": "840015" and with no store for the national online price, and join the results on ean. That is how the table above was built: 32 searches, 32 credits. For one product, /product with ean and store does the same in one call.

What this does not tell you

• Which store the poster meant. Several Carrefour stores sit around Place de la Nation. The closest Carrefour to Place de la Nation, the City at 27 rue de Picpus, has no online prices (store_ref: null), so we priced the nearest City store that has them.
• One day, regular prices. These are prices on November 12, 2026, without promotions or loyalty-card savings, which the API flags with loyalty_only but does not price.
• Other chains. The thread compares Carrefour with Monoprix, Franprix and Auchan; this data covers Carrefour stores only.

The same question about whether carrefour.fr prices are national or local was asked on r/AskFrance; the answer is that the site shows a national online price until you pick a store, then that store's. The same pattern holds in the US: see Whole Foods in-store vs online prices and ALDI app prices vs in-store prices. Every Carrefour endpoint is walked through in how to get Carrefour grocery prices, and the data options are compared in the best Carrefour grocery price APIs.
