According to this:
https://www.hertz.com/rentacar/hertz...eview_2017.xml
being a GoldPlus rewards member nets you an additional discount of 5% on rentals (for a total of 25% in the US). However, when I try to make a booking from my account, I cannot select the CDP "HERTZ 2017 Q4 SALE GOLD" on the booking form.
Has anyone been able to use this offer? Is there a 6-digit number for this that I could type into the "other" CDP field?
