I am sympathetic to the collectors who did not get their stuff in a reasonable time but that issue has been addressed and explained, so why not give the AH a chance to get it right, or use the direct contact info that Ken provided instead of railing here?
With regard to the pestering exhortations to pay, there is a simple solution: don't. If you want to pay by check and that is an option, just do it and send the emails to the trash unread. No one has to do something just because someone is a pest. Just Say No (I think I read that somewhere).
