Submitting galleries
 

Would like to know if you submit freesites and you are doing ok with them (sales wise), should you start doing tgp's too? It's pretty much the same thing, just more hassle and investment or atleast that's how I see it.
What do you think?

If you're already building free sites, then submitting the galleries is just an investment in time.

There is a difference between "doing tgp's" and doing galleries.

If you already have hosting, content, and the tools necessary to build free sites, then the only investment galleries should take is a time investment, as Greenguy has pointed out.

If you are talking about building your own tgp's, then yes, more things are involved.
