I'm not sure if they have any of these left in stock, but they also have the metallic front pockets listed on sale and the large version too. Good luck.
I purchased this bag on sale at Nordstrom (different color) a couple of weeks before Christmas. Also, I think Net-a-Porter had a metallic one on sale before Christmas. Aloharag had the large pocket during their last sale. So the answer is yes they go on sale. If you have a Nordstrom, you may want to check to see if they still have any on sale. Otherwise, I would suggest holding out to see if any go on sale in a couple of months as spring/summer items start coming in.
