O_o I did. I technically purchased Deep normal, without realizing the student discount, then a bit of time later I noticed it, and asked to be upgraded to Deep + Animation educational and they managed to help me there.
But Goms prices are correct, at least at prepurchase rates.
The process is to email planetside, wait a bit, and probably give a shout out on the forums here that you did so (so they actually check the spam filter as half them seem to go there).
And they can set you up with the student discount.
