I need to clarify something, as I just got a question - if you buy a 4 volume set, we ship them in 2 boxes, Vol.1 & 3 in one box, Vol. 2 in another box. We (try to) ship orders to the same address on the same day, but there is no guarantee that the post office will deliver them the same day. I can see a scenario in the mass shipping we did where one box may not go out the same day as another for the same order. If you get one box one day and nothing the next, contact me and I'll try to find your order in the list and see if I can track it.
All of the domestic pre-orders were mailed by Oct. 2 though.
