I've used some that deliver "traffic" for as low as $.005 per "click". It isn't robot traffic but its not exactly a click either. It's a pop-up or under. Whereas the signup rate for the site from G traffic is typically between 1 in 20 to 1 in 35, this type of "traffic" was about 1 in 150 and some people from it did end up becoming paying members.
