I ordered two 2.6/16/512 rMBPs on the same day, at the same time, shipping to the same address, both via the Education store. One went into Preparing but the other hasn't. What gives?
Apple's idiotic order processing system is a scandal. Once I get them both and they both check out fine, I'll write them a tersely worded (though by no means rude or hostile) letter of what I think of this aberration where people get their rMBPs in all sorts of nonsensical orders, like the untold numbers of cases where someone has been waiting two, three weeks already, and someone else orders the same thing and gets it shipped three or four days later.
They always tell you that it's first in, first out. That's a complete lie, through and through. And rather than acknowledge that and simply apologize, they deny even the remote possibility of this happening, when it fact it has happened many times and will keep on happening unless they get their act together. Never mind that they don't return calls or reply to emails as far as I've experienced so far. Their customer service stinks.
