Had similar rural delivery problems. With Amazon and others the post office is having to fill gaps it was not used to doing.
Talked to the post master at my local PO and asked what I could do to make easier for them and myself. They were very helpful... better than trying to communicate with Amazon
Postal regulations require an approved box and key type for delivery.
US Mail is protected unlike UPS, FedEx etc.
Getting Amazon to stop delivering thru Post Office doesn’t seem to work.
I even typed “Do not mail USPS to this address” then listed my address in the same line and Amazon and others just ship it and don’t care about the difference between mailing and delivery addresses
Approved US Postal boxes can be a bit pricey but getting a single box is not bad. I had to have a place they could pull off the road safely and was already on their route.
Amazon, UPS etc usually can’t share same box if keyed for post office
I have also made friends with my regular mail carrier (and her substitutes).., cookies, dark chocolate covered almonds ha, ha. ..and have better service because of that too.
Have found all of the people there to be good folks.
My carrier has been great, however, they use the little scanning device to GPS track them. So they (Management) know when he goes up someones driveway, and when he goes backwards.
I don’t want the guy to lose his job over it.
I have adjusted where I get what I need. I do a lot of car stuff (Used car guy) and ordering parts from amazon was always simple/easy.
now I am using rock auto more and more. At least there I can select who is bringing it to me.
I did cancel prime and told them “USPS won’t deliver here and that is who you keep sending”
well that and grand tour seems to have fizzled.
