Reproduction Tail Light And Reverse Lenses 1965 Valiant or 1964 - 1965 Barracuda

Will other board members please give me your opinion?

Does a seller have the responsibility to make sure the package is delivered to the buyers door? The package is at the buyers local post office but he refuses to go get it. Does the buyer have any responsibility to retrieve the package once it has arrived?

Has the USPS ever done this to you by stating the delivery information was not updated? I have seen this message for when the package is at the office but they have also used it after the package was delivered.
