Struggling to keep track of your supermarket loyalty cards? Do you often leave them behind at home?
"Darn, I forgot my loyalty card again!"
As a daily commuter and savvy shopper who's tested countless organization tricks, here's a reliable tip to avoid checkout regrets—especially for Navigo or Imagine R card holders.

Simply slide your mini loyalty cards into the plastic pocket on your transport card.
There's just enough room—it feels purpose-built. Stack up to 3 cards one behind the other (see photo).
As shown in the image, I've kept my Monoprix, Dia, and Auchan cards there for months without issue.
This method ensures no more oversights. Your loyalty cards are always at hand, unlocking discounts every shopping trip.
