P.O. Box or other address?

Ordering seeds and wonder if anyone has them sent to their personal P.O. Box? I'd prefer to send it there, but I'm not sure if that is wise. Any personal testaments to ordering to a P.O. Box? I live in a small town and wonder if Granny who puts the mail in my Box might get curious about my envelope from Holland/UK or where ever.

I have a place where I can have my seeds sent to, but will have to give a cover story and would rather try my secure P.O. Box.

dont worry about granny, if its opened then they are in big trouble they start at like 20 an hour to work so they wouldnt want to risk it, most packing is very good so u wont even know where they are in the package it would;nt be in a baggie saying weed seeds u know :D
