I don't live in the US, and I'm not sure if it's the same thing here. Basically I have to personally sign a "contract" with my post office to get a box inside of their building.
How does this protect me at all if I used my full name etc? Is it different in the US or am I missing something?
EDIT: Thanks everyone, I now realize my mistake.
Key goes in, drugs come out. Can't explain that.
