PLEASE SAY NOOOOOOOOOOOOOOOOOOOOOOOOO TO POPUPS!!! (a thousand tiny babies are weeping at the sound of your nonsense).
Why not buy a hammer and go around and pound people in the knee cap until they buy from you? That's just about as awesome as using popup.
Here's a better plan -- be so bad ass that people automatically want to get in bed with you. They're asking for your details, huh? How about that?
