What is better these days: UPS, FedEx of USPS?

Zoid,

You aren't using the actual PO box address. You're using the Post Office's address and the USPS branch has been kind enough to deliver the packages to you. That isn't common and it is definitely not the same thing as using a PO box as the shipping address. If you entered the PO box address as the shipping address, UPS and Fedex would not deliver packages to it.

Indeed; maybe I mis-explained it. Still and all, my PO Box can serve as a courier shipping address, per se. Just wanted to clarify that.
