I bought my tickets to the Tacoma, Wa show during the LPU presale for $80 (after taxes and fees). Yesterday I reading the forums and one person said they payed $100 after fees and taxes. After a little more research I found that one show will cost concertgoers $170 (I think the show was in California). So my question is "why the price difference?" Are prices based on expected ticket sales? I just don't understand how the same concert/tour can double ticket prices at different venues.
