Oh yay! A package from Amazon, delivered from usps, in a brown paper envelope. It was left out on top of our mailbox and hubby brought it in dripping wet! Did I mention that it rained pretty much all Sunday afternoon. I know it was a substitute carrier because our guy (Shayne) always brings them to the deck. So, everything in the envelope is dripping wet. What is wrong with you people?!?


Never has there been a worse delivery service. Literally ran and dumped packages about 15 feet from the front door. Cause, well, who wants to walk 15 feet to an area that does not get hit by the elements when they can just not? Love my regular postal delivery person, but when it is not her, wow, they could not care less about their jobs.


LOVE this post has adequate staff to service customers promptly. They are knowledgeable and always helpful, friendly - no matter if it IS Christmas rush. I feel so much more secure about receiving ALL my mail and parcels at this office instead of home delivery as in the old days. And I thank them for the new, extra services, like having parcels shipped to the PO address instead of my home, when shippers require a street address. Great new feature which I've used a lot. Keep coming up with these good ideas. Great people. Thanks for the service.
