Continuing at Apple, purchase a MacBook, MacBook Pro, MacBook Air, or iMac from the Apple Store for Education and receive an $100 Apple Gift Card for free. That’s the first free gift card offer we’ve seen from the Apple Store, although last year’s promotion included a free iPod touch instead. This offer is valid only for qualified students, teachers, and staff. The gift card can be redeemed online at the Mac App Store, the App Store, the iTunes Store, and the iBookstore. Deal ends September 20.
