The prizes (Macbook Air & iPad); are these for US residents only? Unable to find any info in either the FAQs or the T&C
Let's do some math:
Let's say that only 4000 people buy the bundle (highly unlikely, probably much more), the cost of the macbook and ipad is $2000 Your expected value from the prizes is $2000 / 4000 = $0.5.
$0.5 / $79 total cost = 0,6% wow. great.
