So you're saying your carrier DELIVERS your mail? What a concept.....
I had an email the other day that my package had been delivered to my front door at 10:48 a.m. It was finally in the mailbox at about 3 p.m. I knew it was pointless to call and complain, but I was pretty impressed that it arrived the same day. My mailbox is NOWHERE CLOSE to my front door since our driveway is about 800 feet long.
I often get delivery confirmation saying it is here, and then I get it days later.
That's how USPS works here also. My driveway is only about 450 feet long, but you can't see the house from the road.
