“John, thanks for providing us with your specialty retailer and catalog databases. We have sold more than 3,000 copies of one of our books to customers from these two lists...none of whom had ever ordered from us before. Well worth the $60 we paid for the two lists!” — Steve Deger, Sales and Marketing Manager, Fairview Press
