Thanks for the suggestion Yael.
The rep was hopeless. Just gave me a line about sellers needing to contact bidders if items were damaged during the last 12 hours of an auction.
This person has sold a stack of travel guides lately (and not much else) - it's not too hard to match names with listed entries in the white pages and get addresses.
This person potentially has the addresses of dozens of people who will be leaving their homes vacant in the next few months and the rep seemed to totally fail to grasp the implications of this.
Maybe I've been watching too many movies but my spidey senses are tingling about this guy.

ETA - normally I don't bid with low feedback/new sellers but for a $5 book I figured it couldn't hurt.
