You need to keep checking. They usually update stock early in the morning. I was looking for a watch Friday night and every store in Southern California (and there are a bunch) had none showing for store pickup. I checked a few times in the wee hours and right around 8:30 or so, every store around me had the Space Grey 44MM ready for pickup. Snagged one yesterday.
As we speak, a store 14 miles from me has them for pickup. You could always have a friend/relative pick it up for you and ship it to you.
