Have you checked out the Vans Warped Tour website lately? The ticket price is discounted by at least $5 off the regular price of the tickets if you buy them through the presale here:

All of the concerts have discounted tickets available, not to mention the fact that the presale is also offering the 2008 Warped Tour Compilation album for $3.50. You can also buy an exclusive T Shirt and discounted AP Magazine subscription that comes with a cool "Cut the Warped Tour Autograph Line" pass!
