Money saving app for all the main stores (Geant, Carrefour, Leclerc etc.)

I'm in the UK but holiday in France and I've just signed up. With LeClerc who we normally shop with, there is no need to have a loyalty card with the app from the looks of it so how do I claim the 'reward'/money off?

Auchan is on the site too Lis.

No there are currently 64 products on special offer. They seem to be the same ones in each store so if you buy Lavazza coffee, you can buy it anywhere and still get a discount. Not sure how it all works yet as still playing with it!

I have fidelity cards with Intermarche, local baker, Auchan, Castorama and more, so I get discounts now and then, even the local cave in Rognes... :)

Is it just the 8 products displayed on their website that will "earn" you money ?
