I say god bless them, they can have the $1. The hours that the box office are open, and the ease and efficiency with which you get your tickets is really astounding. Appreciate it (I'm not chastising you -- I've asked the same question in the past, but having dealt with *many* more clubs since then, I've changed my tune).
The answer on the ticket price never being actually available will be this, "you can pay at the door night of the show, and it'll be the listed ticket price." Yeah, like X won't sell out. But, it's a formal (and true) answer.
And as to the 9:30's $1 in particular, compare it to Black Cat -- which I love, but it's a pain getting advance tickets there. You gotta bother that manager guy with the long hair (can never remember his name), and though he's always nice, it always takes a while and I feel like I'm interrupting him. And you *have* to pay in cash. Big pain if you're getting a lot of tickets.
Just my 2 cents.
