JC Penneys will open Sephora stores within their own store starting this fall.  Sephora will be the exclusive seller of beauty products at JC Penney. I think this is a good move by JC Penney, maybe they read my entry JC Penney’s Creates Temp Store in Manhattan Putting ‘the City That Nevers Sleeps’ Asleep”. However, I’m not sure if this is such a good move for Sephora.
