I'm not the only who got that deal. Everyone who has attempted to get in on that deal was able to do so. Two data points: my daughter bought one and I bought one.I really don't understand how you got the deal. The student coupon says $150 off REGULAR price, not sale. So it'd be $150 off $999 not sale price $899. And the coupon says it won't work with other offers/deals.
According to one of the guys at Best Buy, the "$100 off" pricing comes directly from Apple, it isn't a Best Buy-initiated deal.
