AARP Discount?

The week after I got my AARP (association of retired persons) membership in the mail, I ordered textbooks for my first year. I decided to call to pay rather than do the dirty deep online. The clerk at the bookstore sounded to be 20 y/o tops and almost screeched when I asked her about an AARP discount for the books. Apparently, it is not usual for folks to ask for that discount to be applied to book purchases in medical school. I'm not sure, but I think I'm the oldest in the class. I'll find out soon enough.
