Hmmm.... I think the problem may be with USPS because they generally don't provide a tracking number for all their packages. It used to be as a prime member all my packages were shipped via UPS. It didn't matter what it was. Then things changed a couple of years ago and things like CDs, blu-rays, and small items were shipped USPS. The items still arrived in the promised 48 hour time frame, but only the larger, big box items were sent via UPS. That's when I noticed OnTrac because the way they allowed you to track the package changed. Some packages don't have tracking information and I think those are the USPS packages. Also, I think OnTrac may be linked to the tracking and package notification system. I get text messages when my packages are delivered.
I hope you get your items, but thanks for letting me know of your hate, man!

t: I gotta keep my eye on Amazon to make sure I don't need to hate them too.
