Problem, Mank, is accessibility of tickets for customers who want to go to these shows, but may live too far out (or in another city) or work hours that bar them from getting to the club. Trust me, few despise TicketBastard more than I, and I may buy tix for 4 to 5 shows a year from them, out of the 50 I go to.
I think the 930 Club *tried* to help by going with a TicketBastard competitor when it started up. Alas, there haven't been anymore, so that simply raised the ability of tickets.com to raise 'costs' to meet TB.
It's an especially big problem for folks like those here on the board -- we go to smaller shows and venues with lower ticket prices, so a 50% markup is INSANE. I don't know what the answer is; I wish someone would find one.
