I am not asking for undeserved National discount codes. Rather, I am asking how might I obtain some, perhaps by joining the right organizations or checking where I might already be entitled to a discount.

Costco membership: Avis, Alamo, Budget, Enterprise but not National
AAA membership: Hertz, Thrifty, Dollar but not National
my own alumni association has Hertz and some others but not National
USAA membership: Not National



National seems hard to find. Anyone try to get their own personal discount code from National? Or maybe convince an organization that you belong to try to get a National discount?

NEA (National Education Association): National. Non-teacher membership costs $25.

Disclaimer: I am not asking for someone to post "xyz company code is 12345" or "university of abc is 56789". Rather, how might I get a code by joining an organization or having some legitimate tie to something.
