What the GPL says is that IF you sell or give away the binary, you
must also provide the corresponding source for no more than (ten times)
your actual cost to transfer it, such as the cost of a CD-ROM.

The words "ten times" apply to the GPLv3 only.

There is nothing to prevent you from selling source alone, or from
selling source and binary together.  Economic reality plus the GPL
rights will tend to drive the cost of source down to the transfer cost,
however, as once anyone has the source, they can freely redistribute it
to anyone else.

There is nothing in the GPL about "reasonable price".  The FSF itself
sells sources and binaries for the entire list of GNU software for
US$5000 per copy, the same things you can get on line for $0.
