True, but I am assuming most peoples shipping says you'll get it by end of day. If they arrive at 1am and you have a 1-2 hour turn around they leave at 3am. Looking at flight times the longest flight time in the continental US from Louisville is like 5 hours max. So that puts phones in an area at 8am (but this was also going to the west coast so save a couple hours with time difference). They can easily load up a truck and get it to you by end of day.
I think most people think they have to have a truck loaded in the morning and that's it. They'll keep loading up trucks throughout the day if they need to.
