Disney is now honouring discounts on the Suites, but the available rooms are limited. With just a little less than 200 Suites in total, and (at times) overlapping discounts (such as a Disney Code and AAA), you might not be able to get one on a discount.
Early August is still fairly busy in terms of attendance, although not one of the worst times of the year.
My suggestion is to call EVERY DAY. People often book/hold on a discount, and then either let the hold expire or cancel the ressie. If someone cancels a discounted ressie, it goes back into the system, and if you call at the right time, you can hopefully get it.
In the meantime, if you are definitely going to Disney at that time regardless of staying in the Suites, book a ressie anyway, and keep calling. If you get lucky, cancel your other ressie and get the Suite on your discount.
Good luck!
