marill999,
the same thing happened to me too, but i actually got the drive a couple days ago. i know it was heavily backordered in LA, and i've also been hearing it's pretty bad over in NY. that sucks though... just keep emailing and calling them about it - keep complaining. yea, i'm kinda unsettled that i was one of the first to order this on the 13th and ppl who ordered on the 14th or after me got it a couple days later. the only thing i'd worry about is the postmark date(14 days from your order date). i'd mention that to the CSR the next time you call them as well, and just chew them out about it.
DaveR,
i'd give WD a call about the postmark date. it's so lame that you HAVE to get it in within 14 days of the purchase - that's actually a rare instance! the most they could do is to extend the date for you to get it in, so it's worth a shot.
