The USPS Informed Delivery 'Daily Digest' email states at the top: "Coming to your mailbox soon." Typically, what is shown in the email arrives in my mailbox the same day, but occasionally it arrives a day or two later.

So glad Sandy my mail lady got a new postal vehicle A Mercedes van with A/C, this summer in her old beat-up vehicle with no A/C I thought she was going to pass out one day.

I have seen several of the new vans around town, I guess they did a fleet order.

If you are having issues with the USPS particularly issues involving theft or fraud, I have found the following links may be helpful. It appears the local PO only reacts once issues are escalated to a higher authority. I have had some positive responses using these 2 methods. We were having issues a few years back where packages were being "delivered" on Saturday when we were closed and outside business hours and going through the local channels was fruitless. Once I filed a complaint at a higher level, I was shocked to receive a follow up with 24 hours and a resolution to the issue.

I have read on this thread that packages are showing delivered only so they can be cleared out of the employees scanner. That is fraud and not looked on fondly by those at higher levels despite how convenient it may be for the local USPS employees.
