Roger C. Parker tells us that the best time to resell a customer is when you are delivering a previously ordered item. Says Roger, “I buy railroad books from www.karensbooks.com. Each time Karen ships me a book I've ordered, Karen includes her latest catalog. Within a week or ten days, I invariably order another book...or two.
Enclosing a catalog with each shipment makes a lot of sense. My awareness of her firm is at its peak when I'm unpacking a new book, I'm pleased with it, and--being happy with it--I soon will want more in order to continue the pleasure.”
