later today, we went to an "Ausan" the French supermarket chain, they have many here. We found it without any problems. At the weekends the roads here are more normal for driving and less packed. We spent another 150 pounds on more stuff. Consequently, we won't be shopping except for milk and veg for the next 3 weeks.
Ausan is huge and my eyes got bigger when I saw all the cakes. See photo.
