For those of you that took advantage of the Apple Back to School promo, are you able to use the gift card on accessories? Or just in the App Store, the Mack App Store, and the iBook store? I was planning on getting mines from Best Buy, but if the gift card can be used on accessories then I'll buy it from the Apple store. However, I don't know if I want to venture into the mall and that supre busy Apple store at Lenox if the card can inly be used on the app stores. EDIT: Found it.
