Thanks Gina! The method outlined on the first page of that thread didn't work for me. There was no link to National on the partners page.

I then worked backwards from the end of the thread and used the code that you gave in your post a couple of weeks ago.
Here Since we are going for 15 days, the rental is still

, but with the code it's about 60% of the regular price. And the code includes all the insurance.
Edited to add: I found a different code in that thread,also for National. The price it gave me was insanely low. It doesn't include insurance, but my own auto insurance will cover me. The code is: xz53043
