It’s a good time to order from the RAKwireless store at the moment as they have 20% off of a lot of things or 25% for 3 or more of their Meshtastic starter kits. I just ordered some more myself last night!

I’m not sure about the shipping unfortunately. Their shipping policy doesn’t seem to say anything about shipping to a PO Box. I’ve always had shipping to my home address. They use DHL for shipping to me in Australia although I’m not sure if that is the same for other parts of the world.
