I think Apple requires some proof of attending educational institutions or being connected for the educational prices. And they do do some checking according to their website.
Audit Rights
Apple routinely audits the purchases of customers at the Apple Store for Education to ensure that all purchase conditions have been observed. Should we discover that you have not observed all of the conditions applicable to your purchase, you authorize Apple:
- If you placed your order by credit card, to charge to your credit card the difference between the amount you paid for the delivered goods and the price that Apple charged the general public for the same goods at the Apple Store, in effect on the date that you placed your order; and
- If you paid by a means other than credit card, to (a) invoice you for the difference between the amount that you paid for the delivered goods and the price that Apple charged the general public for the same goods at the Apple Store, payable in fifteen days from the date of the invoice, and (b), should you fail to pay the invoice when due, institute legal action against you in a court of competent jurisdiction, with the prevailing party entitled to attorneys' fees.
