I bought a comic book from amazon just recently and the estimated delivery date was the 7th of March and it arrived today, a whole month early on the 7th of Feb and it was shipped on the 24th of January, exactly 14 days. That was just the standard normal cheaper shipping.

I think my Unicron arrived exactly when the tracking info said it would. But that was a mess but only because my post office messed up, not amazon.
