They're shipping from LA, so the people in LA are going to get theirs first. I'm in Florida and got my notification two days ago, so I don't think the shipping order is being prioritized by location (in the US at least. They may be shipping international orders out later? I haven't heard from anyone outside the US getting their notifcations.)
Well that's good to know at least. I wonder if it's just going off order number or something. All the previous prints I've bought have generally all shipped out at the same time.
