They have an answer for that:

"Shipping is 2 day." That doesn't mean it will be shipped as to arrive within two days from ordering, but when we ship it (which may be that day, or may be three days later) you'll get it within 2 days...

The two days before you received the package was two days. QED.

Oh to be clear, I think that explanation is BS, and Amazon is just lawyering the answer. But that's how they see it.
