I don't know your personal situation, but my dealer still shows a "Thank a hero" discount of $750 through 12/31/2011. I qualified when I purchased mine earlier this year. All you need is a copy of your DD214 if you're a vet or proof of active service if that applies. My dealer took if off my purchase price and was re-imbursed by Triumph later.
It also can't hurt to call more than one dealer and see if you can get a better price elsewhere or use it for leverage at your dealer of choice.
