I am trying to book a Budget Rental Car for the 5x points promotion. The rules say I must enter BCD number U072700 for the 30% off portion of the promotion, which is easy enough to do, as I see where that goes. However, the rules also say that I must enter coupon number MUAZ039 to receive the bonus credits. I have been all over the site and nowhere do I see where you can enter this coupon number. Anyone have any idea where they expect you to put this code in there upon booking the car? Thanks.
