Bread

Bakers tend to open even when all the other shops are closed, and vice versa: you can buy fresh bread on a Sunday but the Luzillé baker is closed on Mondays and my favourite baker in Bléré is closed on Wednesdays. They also tend to be open on high days and holidays but closed another day sometime later as compensation.
Supermarkets
There are three supermarkets in Bléré - a Carrefour, an Intermarché, and an Aldi (for opening times look here). The Carrefour and Intermarché are both pretty good, but for a much wider selection we go to Leclerc in Amboise, that's about 15 minutes drive from La Grange. We drive past it on our way to Lavignon and we usually stop there to buy the basics and enough for a day or two. For something approaching a hypermarché, we go to Tours: just south of Tours there is a long straight road going south with all sorts of large shops including an Auchan, a very large supermarket. Their fresh fish is very good with a wide selection, their meat is all pre-packed but the quality seems reasonable. And at the other end of the scale, there’s a mini-supermarket in Francueil.The village shop in Luzillé, L’Epice Riz, is now in the hands of a very enthusiastic and friendly Michael Poitrinal. In addition to the mini-supermarket, he now offers a delicatessen, a traiteur service (ready made dishes), and a butcher’s shop.
