If you belong to AAA, I would check out the prices in your location. From what I've read here, the prices differ depending on state. I believe North Carolina had great rates, perhaps you could call and order from them.
I recently used Ticketmania. The prices they list include taxes, and they do not charge for shipping. Other websites quote ticket prices without tax and shipping included. They are reputable, and I received my tickets in 5 days. If you subscribe to Mousesavers they have even better deals through Ticketmania. Good luck!
