Enjoy your new truck. "A bird in hand is worth two in the bush." For our English as a Second Language "members", this means owning and driving a single Raptor is worth 2 Raptors that you don't actually own or get to drive. Another old saying that might apply, "Wish in one hand and shit in the other, see which one fills up first."
An acquaintance that works for Ford told me that corporate has never offered an incentive on the Raptor. So, unless a dealer is in business to lose money, somewhere around invoice is the best you can do.
Ford doesn't even give employees discounts on the Raptor.
