Saks Chevy Chase has a small selection of MbyMJ items for extra 40% off. I can only recall the Turnlock Faridah in Saffron. There were also two patent turnlock hobos in magenta/fuschia that's on sale as well.
Saks Dallas Galleria has a red fabric Stam w/ gold hardware for 50% off (around $575 if I remember right). Saw a couple other MJ bags for 50% off, but the red Stam was gorgeous.
Beautiful chocolate patchwork Stam. (I've bought a couple of times from this seller and she always sells authentic bags and purses in good condition). £375 or make an offer.
