If you want to start a mail-order business, don’t do anything until you read this 553-page book. It’s been selling steadily for years. It is a thorough, in-depth study of mail-order. It is, in my opinion, the best book on the subject, period.
— Bernard Kamoroff
I started a successful (still growing) mail order business using this book as my text. It’s the wisest investment of $30 a mail-order hopeful could make.
