I also got the $750, the $500, and 0% for 36 mo from Ford Credit when I took delivery May 22nd.
All on a $100 over invoice "retail order" deal.
The catch is that the Ford incentive deals work on Retail Orders only "IF" your car arrives while the promotion is still in effect.
It can be like winning the lottery so it is best that you never "expect" to get any incentives especially ones that are in place at the time you ordered.
None of these incentives were in place when I ordered in late Feb and never dreamed that ANYTHING would be available for 2011's this early in the model year. I first found out about these promotions in mid April when I finally had a VIN number.
