I actually thought about that, and save for having a dead drop, there is no way around sharing at least an address or PO box. I didn't put the logistics in the post, but setting up the shipment would preferably be set up over email. Which can easily be done with PGP. Even if there was a service that would ensure a package reaching its intended recipient without the sender knowing the destination, the middleman needs to be trusted. But I completely understand your hesitation, and no offense taken. I mean, I'm basically a random person on the internet.
