Living in Switzerland, I often choose to shop for groceries in Germany! Better prices and (much) better range in Hieber. (Although agree that France usually has both beaten.)
Assuming you mean the Hieber in Weil am Rhein, they really do offer a superb shopping experience, but it's vastly above the standard. I wish more supermarkets would adopt the self-scanning devices, it's perfect when buying single-digit items.
