Somebody asked the question, when do I stop calling them? This is one of the common sales problems. If you feel like you're bothering them, you need to rethink how you're doing things. I've been there and I've been stuck thinking, "Should I call? Should I not call?" You're ability to tell whether they are ready to buy or not ready to buy depends on your ability to stop these common sales problems from hitting you square in the face.
