I'm trying to buy the new MBA on Apple's online store but I get to this step where it asks me if I want the iTunes card and there seems to be no way to say yes. I tried with different browsers on a Mac and a PC. I always get this page: There is no "Add Gift Card" button like they say and the "Yes, I want a free $100 Back to School Card." is not clickable. I seem to have no choice but to click the "Continue" button (thus saying no to the gift card) to go to the next step and order. Did I fail to notice a button or is it really missing? Does anyone else have this problem (Canadian Educational Apple Store)?
