Questions about getting a PO box for SN

[TangentiallyAlive]

I really want to purchase from DMC (I'm in the US) but I live with my family and one of my parents opening it is too much of a risk for me. I'm looking into getting a PO box but I have a few questions first:

How should I dress when I'm going to apply for it? Would casual be okay or should I dress formally?
Do I have to make an appointment to apply for it or can I just walk in?
Are they likely to send anything to my address to verify that I actually live there?
I know they'll ask me why I need a PO box. What should I tell them?
What size PO box should I get? Does DMC use a lot of unnecessary packaging?

If someone could help with these questions, that would be greatly appreciated! I believe this is the last thing I need before setting my plan into motion

It doesn't matter how you dress.
No appointment necessary.
They're not going to ask you why you need a PO Box, they will ask for two pieces of identification (such as a driver's license and utility bill)
Doesn't matter what size box. If the package doesn't fit in the box, they'll hold it for you behind the counter.
