On 12/14 I mailed seven parcels. Three of them were Priority Mail boxes, picked up at our house by our regular mail carrier during her regular delivery route. All three made it to their destinations on or ahead of the projected delivery date. The other four were large manila envelopes which I took to the Post Office and mailed via First Class mail. None have arrived yet. Last Friday the tracking service said they were out for delivery by 9pm that day (really??? the Post Office delivering up to 9pm???

). Today it says that two have just left the Phoenix AZ facility and the other two just say they will be "late"
For the most part though, I have no issues with the USPS.....I think they do a good job for the $$.
