Prices of Vans shoes @ Warped tour?

Okay, so I'm planning to go to Warped tour a week from today, and I was notified that Vans shoes will be sold @ their merch tent. People were saying it's more cheaper there, 2 pairs for $60, and a single pair for $30-$35. I just wanna clarify this up so I'm ready the day of Warped..

& Yes, I'm planning to buy a pair ;-;

Thanks!
