Hi. I'm trying to reserve a car through the Hertz web site, and I'm having a problem where the weekly rates go up whenever I try to apply any promotional coupon (PC) on top of the CDP code. I get a pretty decent weekly rate when I apply only my AAA CDP code (36% discount). However, if I apply a PC, the weekly rate jumps up (22% discount instead of 36%), more than wiping out the savings from the PC. How can I keep the AAA CDP 36% discount and apply the promotional coupon? It's the same result whether or not I'm logged in to my #1 Gold account. Thanks in advance.
