Last October, I ordered a handful of small items from a vendor. Wasn't much, just a couple three o-rings and a cheap dripper clone. I think the whole order was like $40. Got the shipping jotice, watched as the package went from their shop to the local post office, and then to the regional hub where it disappeared from the radar. After about 10 days, I called the USPS, who were just SO helpful. "I'm sorry, sir, but I don't have any more information available than what's shown on our tracking page." After a month, I gave it up for lost, and didn't give it another thought...
Until it arrived, fully intact, the end of this April.
The funny part was, on a whim I decided to dig out the tracking number and give it a look-see. It showed it being picked up 3 days prior to the day it finally showed up. No info whatsoever about where it had been the past 7 months.
Between that, and having one of my rent checks vanish into the ether, I have very little trust in the USPS these days.
