Here's something interesting I noticed.

Ordered 10 Oct, 2-day ship, currently "order being prepared"...

Nothing about the estimated arrival date when I view the order on Amazon's web page. However, when I view the order using the Amazon application on Android, I see it says "Dec 10". It doesn't say what that date is, but on my other orders that's the date it is expected to arrive. Not sure what it means, but it's interesting.
