At first glance, this book is great value because it is 2 books in one. The first half of the book deals with the business of copywriting - setting yourself up as a copywriter etc. The second half of the book deals with the art of copywriting - how to write good sales copy for ads, brochures etc.
The 2nd half is very detailed,and I found it very useful and relevant across a number of areas. I especially liked the chapter on writing for the web, which is relevant for today's market.
The 1st half is much less detailed. Given that this is the half of the book which should justify the 'Malking Money..' part of the title, this was disappointing.
To be fair to the author, most British copywriters running training courses/writing how-to books are fairly short on the detail of how money is to be made in copywriting.
I would use this book as a general introduction to the art and business of copywriting. Those serious about making money from copywriting should go on to read Bowerman's 'Well Fed Writer', the best book I have come across in this field (even though it's written for the USA market).
