Pinpointing the most affordable supermarket amid countless options can be challenging. Fortunately, Linéaires magazine conducts a thorough national survey every quarter to compare pricing strategies across major chains.
Whether you live near a Carrefour, Auchan, or Leclerc, navigating promotions, coupons, and private-label deals often leaves shoppers undecided.
Instead of hunting for a copy of Linéaires—which isn't sold everywhere—here are the key findings from their latest report.

(The heading's pun was unintentional.)
Leclerc has held the #1 spot in Linéaires rankings for years, thanks to daily promotions, steep discounts, and private labels matching national brand quality. It's a proven winner for budget-conscious shoppers.
Carrefour's second-place finish is the big surprise. Since Noël Prioux took over last year, the chain has aggressively pursued lower prices.
If you're near a standard Carrefour (not pricier Carrefour Market), it's a smart shopping destination.

Intermarché, Super U, Carrefour Market, and Auchan follow, with discounts that are infrequent and modest.
Neighborhood convenience stores like Simply Market, Cora, Géant, and especially Monoprix—dead last—are the priciest, as they focus on convenience over volume pricing.
Urban residents face a dilemma, with these outlets dominating city centers. Check Linéaires' next issue for updates on your local store.

Drive-through and online grocery services typically offer lower prices.
Digital promo codes provide extra savings without clipping coupons from flyers.
Search for codes before buying. Example: For Zalando shoes, Google "Zalando promo code" to find offers on ma-reduc.com, kelcodepromo, or reduc.fr.
Apply the code at checkout on the site, whether it's an e-commerce platform or online supermarket.
