Quoted from CrazyLevi:If you think they are overpriced, just watch ticket prices. They routinely drop prices if shows aren't selling, and the same can be found on the aftermarket like Stubhub etc.
This is a great point regarding aftermarket. The market fluctuates like crazy so you have to determine your price point and seat requirements and be ready to pounce when you see them - the great deals may only last a minute or two.
I use normally use Seatgeek and only payed $200 for Elton John & $85 for Paul Simon to sit in the luxury boxes at Wells Fargo Center with private bar/bathroom. Payed $75 for VIP at the Tower for Elvis Costello that included parking, open bar and dinner. Could have had a PIT ticket for RHCP at Citizens Bank Park for $63 when my friends all had payed $400 thru Ticketmaster. As Levi said you also have to be prepared to get shut out and find something else to do that night if things dont go your way.
