Recently I had a few packages heading my way from Amazon, one of which was being delivered via USPS. I was not in a real rush for it. Amazon gave me an estimated delivery date of Sunday by 9:00 p.m. I thought that was a little odd but not entirely out of the realm of possibilities given that I have had packages delivered late on Sundays in the past. The Sunday evening the package was to be delivered, I was about to go to bed, around 10:00 p.m., and remembered the package that was to arrive. Not seeing it in the mailbox or on the front porch, I checked the tracking info.
