GPLed software can be offered commercially even if the price is above the cost of reproduction. He could be selling it for hundreds of dollars and still not violate the GPL. But he must include a copy of the license and he MUST provide the source code to his customers (not necessarily inside the sold CDs, but at least a way to get the sourcecode such as a link to a tarball, for example). I am not sure, but it seems to me that stating that the sourcecode is available at inkscape.org http://inkscape.org is not enough. He must himself offer the sources to every one that get the binaries.
I think it should be handled in a coherent way with the magazines distributing Inkscape on their cover CDs: if magazines are allowed to distribute Inkscape only with a link to the source code from inkscape.org, then ebay sellers should be allowed the same. It it is denied, then it should be denied to all.
