Should one be weary of the P.O. Box address? I think JABerwocky has one, and I've seen them for others as well. Not loving the P.O. Box myself, makes me think they're doing business from a phone booth.
FWIW, JABberwocky is wonderful and John Zakour will; probably chime in in a minute to second that. He's his agent.
Trust me, you can't judge just by the address.
