That specifically relates to the cost of providing the source code when you have distributed a binary version. Basically, the GPL says you cant hold the source code hostage for a high mark-up if you have distributed the binaries. It doesn't put any limitation on selling the source on its own (such that it is not part of a written offer of source for having already distributed the binary) and it doesn't set any limitations on what you can charge for binaries.
