Yeah I tried this too and you're right: people will say they will buy stuff, but when it's time to pull out their wallet it's often a different story.

I think that is why point 1 is "Sell," not "Interview" or "Imaginary sell." For example, some people put up a web page, run some ads, and have a complete signup process that once the CC is entered they get a "thanks for your interest- we'll be in touch when we get it built and by the way we didn't really charge your CC."

We've had discussions before on this board about whether or not that's ethical, IIRC.
