Hmm, I thought I could remember my friends saying the educational discount was around 20%. Perhaps I am not remembering correctly, or the discount has changed a lot lately.

I remember larger discounts as well. That said, summer vacation seemed longer, too.

You could check yourself http://www.apple.com/us-hed/shop/buy-mac/macbook-pro/13-inch there is indeed a $200 discount for the high end 15" version. The low end 13" has a $0 discount. Remaining 13"/15" models all have $100 discount.
