Arlington Million Ticket question

[intense]

I'm looking to pickup a few Million tickets for myself, my father and a buddy or two... the ones I want are in the grandstands/reserved boxes and range from 80-100$. I remember last year there were a few promo codes floating around to drop the price of these, does anyone happen to know what they are? There is an option to 'Apply Discount' at the checkout.

Any help would be greatly appreciated!
