Yes! I sent some stuff priority right after Thanksgiving, ID-CA and it all got there in the 4-5 days (for 3 day shipping) it always takes from here. I sent another priority package to CA on the 14th, and it has yet to arrive. Tracking shows that it made it from here to Los Angeles on the 15th. Then it just sat there until the 20th, when it went to another sorting facility in San Bernadino. As of today, that's where it still sits.
I would be less irritated, except their rates for packages weighing anything have really gone up. If I'm paying a King's ransom to ship, I expect faster service. Even factoring in Christmas, this is ridiculous.
