Just use promo code VCOSAVE10SEPT before selecting the Visa Checkout option.
Also. If you need 3 tickets, you can use code FAN4SEPT to get another $4 off. This should stack with the $10 off code so you will get $14 off 3 tickets.
This promo should last through the weekend but can be pulled at any time, so I would grab your tickets now if you are planning on going.
***Just a heads up. You do not have to use a Visa card when checking out. It is just the name of the checkout option.**
