I just bought a new rMBP on the Apple Store website using the education discount. All I had to do was click "education store" and then place my order. When does the credential checking occur, and how do they check? I really hope it doesn't slow down the processing of my order. Last time I bought an MBP (in 2011), I did so at a brick and mortar store so they asked to see my university ID. Simple enough. FYI, I am a university lecturer. I also have a nearly full-time software engineering job, and the latter pays a whole lot better. Teaching is basically a labor of love for me.
