Just got an email from Apple today....
What's going on? How come they are already in stores but still haven't shipped to those who have ordered them?
Have you called your local apple store? Usually they only stock "standard" configurations. If you ordered a standard configuration call and ask them if they have one in stock. If so, buy one, then cancel your order. Likely they will have a mac pro to sell you, but it will not be the new model. Call them and ask.
Since the one I want is a BTO I have not bothered - my local store only stocks the base configuration - YMMV
Edit: forgot to address you education pricing question. Yes an an apple store will honour you educational discount - they will ask you to verify that you qualify (pay stub or schedule, have always worked for me and my family)
