On the launch date of 10.04.2015 you'll be able to buy the new MacBook in the Apple Retail Store. But there is no clear date when you are able to buy the MacBook in the Online Store and when it will be delivered . For example: when you ordered the iPhone 5 and iPhone 6/6 Plus Apple in the Apple Online Store on the preorder date, Apple delivered on the launch date. Maybe you'll be able to order the new MacBook on the 08.04., so that Apple will be able to deliver on the launch date. I'm asking because of the education discount.
