The thrust of this book is that you should exercise great care in doing business with sign companies. All sign companies are not rogues, however; there are many good companies. This book will help customers to single them out, to the commercial disadvantage of the remainder.For those who buy a lot of signage, this book offers a useful aide-memoir. You are probably aware of the endemic problems in some parts of the industry, alert to the risks, and adept at handling them. Even some of the experts, however, might find one or two twists in these pages that are new to them. For those who haven't bought signs before, the book should act as a very large warning. Do not go into the business of buying signage lightly; be well prepared. Not all the 100 questions in this book will necessary apply to your situation; you will have to sift out those that are relevant. No one is suggesting that it is practical, or sensible, to subject a sign company to the full interrogation given here - life's too short! Conversely, an awful lot of these questions are not exclusively applicable to the purchase of signs. If you have taken the trouble to buy a book like this, I assume you are a manager that spends money on signage. But you will, doubtless, buy other goods and services, as well, and I hope the book serves a wider purpose.
