Just like they are forced to buy their books: by putting it on the
'required for this class' list. The school agreed, provided that the PCB
price is compareable to a course book (~ E 50, and of course that the
class would require no other things).

After the class another teacher tried to buy a PCB from students (I was
out of stock at that moment) but he could not find one willing to sell
:)
