FedEx has disintegrated. I used to use FedEx overnight letter service all the time at work to send documents, and it was relatively inexpensive (less than $10). Hadn’t used them for a while and then about four years ago (I’m retired now) had to overnight a document. I was floored by how absurdly expensive it is now, and by the fact that they no longer guarantee 10:00am delivery, or even anything close to it. The service had degraded terribly and the price was astronomical (I think it was around $80 or $90 if I remember correctly).
I had a FedEx hiatus due to winding down a couple of hobbies simultaneously. When I started shipping things again, the FedEx of "now" wasn't the FedEx I knew.
To fix FedEx, they would have to leave Memphis. It’s a labor and conveyor sort technology quality of workforces issue. St. Lois, Nashville, Knoxville, perhaps. This has been identified by FedEx.
