In the Seinfeld episode "The Pie", a saleswoman tells George that the store is having an upcoming "unadvertised" sale, in which a suit normally out of his price range would cost much less.
But I don't quite understand what was going on in this scene. What would a store gain by having a sale they don't intend to inform the public about? And why would she tell George anyway? Was there anything more to this unadvertized sale?
