Not only am I upset that you are going off the scheduled times that USPS are stating for shipping times. You are getting me in trouble with my customers. Even when I get the package out the same day and before 10 AM and driving up to the main Post Office. I am still not getting Priority Mail to people in 1 Day! That is not what is on their website at all. even with Priority Express it can be Overnight or by 6 PM the next day and that is if and only if it is in the right area. (you must read the fine print to make sure your area counts.)
Please change the times to fit the most up to date times by USPS standards.
