Auchan has set up "mystery cart" operations in 45 stores in recent months. In these shopping carts, the French company offers its customers unsold non-food items.

If they do not know the exact contents, they can acquire them at a low price. A video from the Auchan store in Bagnolet, last week, concerning this operation, has also been viewed more than 1.8 million times on TikTok. Since the first event, more than 500 trolleys have been sold in this hypermarket.
