The very best prices will be the military salute that are sold to active duty and those that retired from the military. I have never found anything close to their prices. Maybe you can take advantage of that offer. I work for Dept of Defense and I am not allowed even to get these discounts.
Tickets for Military from Disney Last year when I went to
Disneyland, Get Travel was the best value I could find. With Get Travel, they will be at the Expo so you can pick up your tickets with the race bib. You can google for discount tickets but you may not find anything better. I never did.
