Having not a clue about how the importing business works, I can't verify how accurate this teacher/writers lessons are, but having common sense (at least I believe I possess it) and a generally good sense of reading people, I firmly believe that Spiers is one of those rare people that really enjoys teaching and helping people and has written this book in the hopes that lots of students are going to be successful. I have read (and reviewed) other works where I thought the author was trying to sell something or was simply blowing smoke, in this case I believe.
