What I said was if you are going to open a PO box there is little point unless you are going to do it anonymously otherwise there is no discernible gains to be had over ordering to your home address if you are using your real credentials. Personally I would do neither of those things, I would invest the time into securing some safe anonymous drops that are not linked to you. If you decide to go the PO box route then yes you would need fake docs which as a I also said raises the stakes given the penalties for doing that if caught.
