Question on applying for 1.99% financing

I just placed an order before the 1.99% promotion and my reps don’t want to give me that rate. They said I’ll have to pace another order. I’m nervous because I didn’t get the 6.2% rate they advertised on their site so I don’t know if I’ll get this 1.99%. I have a 750+ credit score though but not sure if it’s worth running my credit just to find out. Any advise would be appreciated
