Has anyone used the TodayTix App? It looks like a great way to buy discounted theater tickets. I was wondering how you get your tickets if it is not a conceirge show where people with red shirts are outside to hand out tickets? Also, is there a strategy...i.e., do tickets keep getting released the week before and prices change? Is it best to wait until day of the show or go ahead and buy the tickets when you see availability show up?
