In the FAQ, under the question "This software is 'free', 
but I bought it from an authorized reseller . What's going 
on?", you have written "But you can be charged for 
duplication fees, or any other services (example: software 
CDroms or shareware collections, or fees for maintenance)".

Do you mean that they may not charge anything just to make 
money? That's not what the GPL says...

As I understand the GPL, a reseller may charge *any* price 
(even $1000) for the (compiled) software as long as the 
source is either included or offered in any other 
convenient way for a low price ("for a charge no more than 
your cost of physically performing source distribution").
