Forget about it.

The place to get Pro is when you get the machine. It will run at most 99USD to move that up a notch. After that you will find your school bookstore to be the next cheapest and after that you are on your own to find a place to sell yout the upgrade.

CNet and this place doesn't sell this product and since we get the OS with the machine, we don't shop around for the last few licenses we need. Your price should vary from 99 to a maximum of 199USD for this upgrade.

As to legalities, that's a nutty issue. You may have to consult a lawyer since I can't fully understand the agreements in my country and don't want to know what agreements there are as you cross countries. Then again, you could just find your upgrade and install it and leave the lawyers to feed among themselves.
