No it is not legal to charge for the software. It is OK to charge for
distribution costs and service, but not for the software.

There are no distribution costs in this case (you do not have to pay to have
your program available at Handango) and I fail to see what kind of service they
provide.

9.95 is illegally selling GPL software.
