I realize this thread is a year or more old, but it offers great advice - Let me pitch you an idea and see if you think it'll fly.
I go to AAA and sign up with them. (new family plan - son in college) Then go to studentrate in a month or so and apply for the 10% discount (using my son's email - I'm blessed that he has the same first letter/same last name as I)
It seems like it would. Your take?
