Margins are so razor thin on hardware like this, there is no room for it to drop anywhere. It doesn't take more than a little logic to realize apple would never allow their products anywhere near this site.
I am sure the people at Massdrop are trained to not only contact manufacturer but also vendors who has overstock of product in order to get deeper discounts.
Zelgiusthebrave, there is many reasons why people choose MacBook Pro over laptop with windows. Not everyone games, and if I was buying a pc for gaming it wouldn't be a laptop. Desktop is much better for this and have more custom option. I myself need a MacBook Pro for music production since my other Mac is now outdated and MacBook Pro is superior in every way to PC when it comes to working with music. Just something to keep in mind before you say that a windows PC is the best option, there really is no best. It's just preference
