After tons of research, exhausting any chance of local sources, and finding a place online worthy of risking a first online buy, whats that safest way to get it landed?

I think MoneyPak seems the best anonymous pymnt. I've read many stories of PO boxes, people using their own adresses, but is there a best way to be the safest if the narrow chance of something bad with LE happens? I truly know I'm being paranoid, but being new I just want a little piece of mind knowing I made the best educated decision. I am going to do it one way or another, just researching the smartest move. I know there's pros/cons to each method, but maybe someone here can teach me a better way that I don't know about. Thanks in advance
