Take "fulfilled by Amazon". Most of the time they ship by USS brown truck and the package arrives at my door. But, sometimes they use SurePost. My point is that I don't know which ahead of time. It's unpredictable. Or, take some coffee roasters. I suspect they are going to use SurePost, so I give my address as my PO Box. Their system rejects PO Boxes. So, I use my street address. The package gets transferred to USPS and ends up at a post office in the wrong town, since I don't have a mailbox at my residence. The USPS won't let me create a mail forwarding address in my residence town, since "I don't have a mail delivery address there", Catch-22. In addition, SurePost claims to accept PO Box addresses, but the vendor's software doesn't know that. And, I don't have a way to tell the SurePost system what my postal address is. Same deal with the Fedex equivalent.
