It's interesting the things that are commonplace and what is more recherché in local supermarkets. I reckon you'd have to look in a larger city or in a specialist shop. (I'd be happy to bring some out at Easter for you!) There's a guy in St Aout market who sells herbs and spices, I think he has a shop in Chateauroux, I bet he would know.
The thing I am surprised not to see more often is Haloumi cheese.
