I've had a sales rep trying to sell me unit testing software for over a year now. We were much too busy to do a proper evaluation of his product until just recently, and I haven't always returned his phone calls or emails. But I never asked him to stop, because I knew that his product was worth taking a look at. We finally got a chance to do so, and now we'll probably buy it. Be patient. If they don't give you strong hints to leave them alone, it's okay to keep up the polite inquiries.
