Amazon Predicted Delivery Times

I placed two orders with Amazon US yesterday evening. I just got two emails from them confirming that both orders had shipped.
Great!
But wait… the predicted delivery dates are a wee bit odd:
Order 1 – estimated arrival date: 28-February-2007
Order 2 – estimated arrival date: 14-March-2007
That’s bizarre to say the least!
Both shipments are DVDs and the first one has two boxsets (Firefly and Mission Impossible Ultimate Edition)
It doesn’t bother me that much, as it will give me something to look forward to, but I do find it odd 🙂
