The web site was working fine for me -- while I didn't find any cool luggage or bags (I was hoping for a quirk of fate that the Cruise Line Gucci Tote would be on sale -- no such luck)....so I ended up getting two Marc Jacobs by Marc Jacobs shirts, a pair of Prada loafers and a Lacoste cashmere sweater -- all for under $500 with tax and shipping.
As for your question on whether to call tomorrow -- you can call the 800 number tomorrow I am sure for help on Saks.com. But if you were looking for help in the actual stores or wanted customer service to help you locate an item in the stores -- you may be out of luck. I have found that even when the 800 number says that an item is in stock in Store X -- their inventory isn't always right.
In any case -- there is a huge box under our tiny Christmas tree and I am dying to open it!!!
