Here in Norway you don't have to verify that you're a student.
At least not as far as I know.
A colleague of mine, who has a daughter who's a student, ordered an iMac with the discount. He was not asked for proof.
I just ordered a Macbook Pro with the discount, I was not asked to verify that I am indeed a student at any point during or after making the order.
-for the record I am registered as a student with a Norwegian University; taking a course for work.
However I was considering ordering my new Mac with a delayed payment plan, I called Apple to ask how that would work and they said that I would get 48 hours to e-mail them proof of my enrollment at an authorized university.
So I'm a little interested in how it actually works.
Because it seems like it just works on the assumption that customers are honest people who only shop with the discount if they know they're entitled to it.
Maybe Apple do random sample test? -every now and then they select someone who's shopping with the discount and ask them to prove they're entitled to it?
