Im sure like any other DNM user when I have pack(s) in transit, I hawk myUSPS every second I can. Not until I was using this service did i realize how often USPS misses their own deadlines. For the second time in the last three or four months, an express overnight package was stuck at "departed regional facility" for over 24 hours passed the scheduled delivery date and only just now updated but is still "departed" the same facility. Ive also had countless priority packs delivered the day after scheduled delivery date (usually firt thing in the morning). It happens. Dont freak out. People make mistakes, and the USPS is far from a perfect (or even efficient) machine
don't check usps on your home internet kids!
