Also on RAM the rebate is based on where you are going to register it, not where you purchase it. We Live in Washington State and bought in Colorado, and they had to verify the rebate at the zip code we were registering the new truck at.
We also had to pay Washington State sales tax on the $3K rebate amount on top of the money actually paid for the truck! Dealer discount was not taxed.
Why Colorado? It was the last 2015 we could fine in Sept that matched closely to what we wanted and we did not have time to order and leave for Arizona after Christmas, and is was a no hassle 11K+ off deal.
