Interesting. I've had problems with all of the carriers (and some that are no longer around), but for the most part I'd be willing to "forgive" Amazon for the transgressions of a third party that's going to screw everyone equally. I've less sympathy for Amazon's own logistics company though.

Timing of residential deliveries are pretty unpredictable with FedEx and UPS in my experience. One of the nice things about having a PO box is that packages are available for retrieval by 10 AM.
