"way cheaper"?! That's intriguing. Which resellers and price are you referring to? I may want to get myself one. How do they compare to Apple's educational pricing -- which is $100 less than normal and, with back-to-school promo, comes with $150 gift card.
The retail discounts I've seen are typically on base models and, often, are less than $100. When spending upwards of a $1,000 or more on a Mac, that doesn't seem "way cheaper" -- simply a bit cheaper! And, no match for educational pricing with the back-to-school promotion.
It always cracks me up with MacRumors reports "lowest price ever on X" and links (probably 95%+ of the time to an Amazon sale) that is limited to one particular model, color, and base RAM, and can be as little as $70 off! 😎
