I'm in the market for a MacBook Air. I can save about $100 on Macmall compared to the Apple store due to the lack of sales tax from Macmall (even with the student discount on Apple's site). Is it worth waiting for the Back to School special? Do you think there's a chance that it will be >$100 value?
From what I have read here (based on other users experiences), It is usually easier to handle returns through Apple.
