Smart? The refurb discounts are usually a better deal, and come with the same warranty. And don't require misrepresenting yourself to take advantage of.
In the UK they dont check either. I'm a university alumni and am eligible for a discount, however its not behind closed doors or anything. They even give you the 2 year AppleCare upgrade here. It's a fairly hefty discount too. I've been using it since I was back in College and have never had to send off any form of College/University ID.
Oh and the refurb deals for us are never anywhere near the edu discount, which is around 15%.
