They had private sales off select items from last week up until today i believe. general sale is Jan. 11 as already mentioned but they might start private sales again a week earlier or so. Most stores in Paris follow this practice. Most time all you need to do is inquire if there are any private sales going on ("ventes privées").It's basically just a way stores have found to get around the very strict and government regulated official "sales period ".
