I'm planning to buy a 2012 MBP the first day they are out in store because my Dell is about to fall apart. My concern is that I just graduated from undergrad this year, and so my undergrad ID card is expired (it says so in plain text on the front), and I do not yet have an ID card for my grad school (won't get it until I'm there in the fall). I have an active email for both my undergrad and grad schools though. What kind of proof do I need to bring in store to get the education discount?
