You won't find a discount. We've been going since 2009 and are yet to find one. We didn't find a deal until we went through a TA this year. Now we're kicking ourselves like "why didn't we do this sooner?!"
As a PP mentioned,
Free Dining is available until 12/23.
I'd throw this idea out there: the Disney Visa card offers interest-free financing on Disney World vacation purchases for 6 months. We save up some money in the months before the trip... after the trip we pay it off over 6 months. You need to be very diligent, but it's much more palatable than seeing $8k come out of your wallet right away.
