If you buy online, they send you an email asking for a scan or fax of your student ID. So you must have either a student ID or something with your name on it and proof you're enrolled in a school. I'm not sure if both the shipping address and billing address have to be in your name though, but probably at least the shipping address.
If you buy in the store, just bring the ID or other proof with you.
Look and see if the bookstore on your campus sells them also.
