And the Major in Mac promo (iPod + Mac) expired on September 16th. You should have some time left to send it in. (Two weeks after purchase or 30 days?) My claim is still being processed after being sent in over a month ago.
Just called Apple centre, asking about an edu-discount, but explained that I am currently under 18 and therefore technically not eligible for it. They were very friendly about it and assured me that I'd be able to get it and the iPod rebate
I'm very happy - I've got a great first impression of Apple tech support
