When a reader wrote in that certain shoes on YSL.com were on sale, we literally said, "Bah!", but checked anyway, just since it's our job. And yet, amazingly, it's true. An example: The Jeanne Moccasins, at left, are now $299, down from $439. You know, just in case the Newest Reductions on Net-a-Porter aren't meeting your standards. Good morning.
