Can someone who used the Best Buy trade in program explain to me how it works? Similarly the edu discount (Do I need to have a .edu email address)? I do work for K-12 if that makes a difference. I have a 2012 13" MBP i7 (non retina) 8GB. Pulled the spinner drive and the optical so I'm running dual SSD. I could install a 500GB back into the drive bay. No dents and very clean chassis. With a 750GB spinner drive and DVD drive the trade in is marked as $415 I'm on the fence of doing a trade in and hoping for another MBA deal.
