I have read they do a lot of back and forth footing between shipment placements so they can get it to you without a problem, and other factors involved, but some have to deal with other third party factors during the process and how it breaks communication between successfully purchasing for them to deliver, especially so it gets you your order without them shipping it with granted access and it being a secure location for the package. I don't know, fully though. That's just my guess and I'm still saving up for DMC.
