I think I got it right.  The distributor of a program under the GPL is
allowed to charge anything up to his or her cost to make a copy.  If
his cost is $200, then it is OK for him to charge $100 (or indeed
anything up to $200).  If his cost is $50, then it is not OK for him
to charge $100 (but he could charge $50).

But of course what is going on here may be perfectly OK.  You have
omitted almost all the important details.
