LEADER PRICE ... no one has mentioned Leader Price ..it's right across the road from Cadisco ... LP is a popular food market in France. Many of the locals in the vicinity of Simply Market use this facility.
We live for two months @ Mont Vernon; I walk 15-20 minutes to LP and can find nearly all our needs.
1) If you're looking for America "stuff" forget it! .it's French
2) Alcohol of all sort is very economical. Wine bargains: In France, Leader Price is considered the place to buy your daily wine,
3) Packaged French cheese and meats are A-1.
4) follow the French locals around the Frozen foods (meats, fish, veg) to see what they're buying
5) Baguettes, French pasties are delivered very morning fresh, often hot
6) Because we are on an island, fresh veg., fruit are delivered by container; therefore, daily shopping will inform you. Not tons of choice, but daily! Eggs are Free Range and delicious.
