Keep in mind that Sunday was not a business day.

It's quite possible that the iPod is being prepared to ship or even has shipped by this point. Those quote confirmation emails are sent out far more often than they're needed, due to FTC regulations.

Another explanation for the wonky quotes: You happened to place your order the weekend that the quarter ended, which is a time of craziness and upheaval. The quarter ended Saturday. There was probably a lot of "closing the books out" on Sunday, which might've come into play. Not to mention the fact that it was Easter, and, for once, the Apple Store CS dept was given the day off.

The amount of iPods shipping each quarter, each month and each day is insane. Yes, the quote mechanisms have always been a work in progress, but from the other side of the curtain I can tell you that there have been some remarkable strides in both the logistics and the logic driving the commitments. This effort is always ongoing. But once you throw the iPod into that, it can seem like the whole system is back to square one.

Anyway, point being, it was an estimate, Sunday is not a business day, it was a holiday, and it was also the end of a quarter. Additionally, requotes are sent out more frequently than needed so as not to expose any others to the $10,000 fine (per order) the FTC applies to under-quoted online orders.

Feel free to PM your order # to me, and I'll take a look at it and see how it's going.
