Several times I have waited for a package that required a signature. website claimed no one home and note left. My wife was home all day, each time, and no one came to the door or left a note either at the door or in the kiosk mailbox. Don't trust anything important to a mail carrier, unless you can stand out front all day and wait for delivery


Delivery of packages to the community mail boxes is horrible. We have been delivered numerous packages for another address as well we have had our packages delivered to other addresses as well. So much for attention to detail.


The customer service at this post office is HORRIBLE. I had a UPS package delivered to my P.O. box here and they lost the package after it was signed for by a USPS employee at that location. After returning to the location with conformation from UPS that the package was at their address the employee was extremely rude and did absolutely nothing to find the lost package. He said, "maybe it will show up tomorrow." On the other hand, what more can you expect from an uneducated government employee.In the future I will have my expensive camera gear shipped to my house and risk it sitting on the door-step rather than putting it in the hands of the USPS at my P.O. box, which I thought was the safest delivery option.
