Does anyone know if the Apple stores will let you pickup before your slotted time? I had to pick a 2:00 time slot as none others were left but wondering if I can go first thing in the morning. I got a space gray aluminum but want to go early to see if they will have space black SS. If they don’t have any walk ins available to purchase, I just want to get my aluminum and go. Anybody have any experience with these pickup slots?
