Here's a new data point. Been watching stub hub for a concert for tonight. There were still tickets available for better seats at face price on Ticketmaster and tickets were listed on Stubhub for almost twice as much which made me wonder why anyone would buy those on stub hub.
Anyways, concert is at 7:30pm and Ticketmaster online sales closed at 5:30pm. So now Stubhub it is. Playing a game of chicken watching the number of available tickets slowly going down to zero!
