Nope. The only place the GPL talks of no charge (or rather "for a
charge no more than your cost of physically performing source
distribution") is when you distribute a binary and have to offer to
provide sources (§3b).

Not only trouble, but explicitly forbidden, the GPL is very clear on
this: "You may not impose any further restrictions on the
recipients' exercise of the rights granted herein." (§6).
The original authors may impose such restrictions on you because
they're not bound by their license(*), but you may not impose these
restrictions on others, so if the original authors would require you
to do so, you may not redisitribute it at all, §7.
(*) As long as they're the only copyright holders. As soon as they
incorporate any code from others, given to them under GPL (and
according to their AGB, they seem to want to do so), they would
be bound by the GPL themselves and it would be illegal for them
to distribute that code under their AGB.
