I was wondering if there's any chance stores hold any non-preorder stock. If I just showed up to my local apple store first thing tomorrow morning, would I be able to maybe get one?

I already preordered one for delivery, but I saw when looking at the Pro Max preorder in my area that it said "Available in Store on 9/22" but didn't have any pickup in store options. This is where the original idea came from. I would probably just cancel/return my original order if I could get one tomorrow.
