USPS Boxes have been arriving in the normal time frame that I'd expect. Most of the flat mail we receive is junk mail and there is little time between when I take it out of the box and it sails into the garage trash can. Certainly not interested in looking at the post mark so its hard to say when they were sent. My wife's sister passed away suddenly on the 21st. She got a
lot of flat mail sympathy cards which she kept, along with their envelopes. Their postmarks indicate that they came within 2 days but most were sent from within the state. Speaking of UPS. I got a set of running boards for my new F-150, They arrived in town last Friday at 12 noon and I got the package today, 4 days later. I could ride a bike to the UPS depot in 2 hours!

It took less time to travel from California to the local distribution depot than it took to go the last few miles to me. In their defense, they're usually pretty prompt with standard delivery, as is FEDEX.
