What exactly is google "smart pricing"?

[tibtraips]

I find the site http://richgame.hyperbiz.info
nice design template and fair game.
I think we can win the game more than 40%

The site looks ok, but have you tried them? When you visit http://hyperbiz.info/ they've got something about scripts with resell rights, hope that this is not a demo script.
