This book is recommended by several lecturers, and is a required 'core' text book on my course (Buyer Behaviour).
Whilst I have no doubt in my mind that it is both a thorough and complete book, the author has given it his best effort to make it one of the hardest books to read.
It is not engaging, it is not stimulating, in is tremendously difficult to read, it is hard to see which of his theories he is not contradicting, the list goes on.
In some parts of the book, you almost feel that the language is difficult on purpose, so that he can impress the academic community.
I read many other marketing / buyer behaviour books, among them Kotlers / Fill / Cambell. It is a shame that East can not take a leaf out of those books! Easy to read, easy to make notes.
If you enjoy / read books by the above authors, do not buy this book. You will be in despair before the evening has ended.
Caveat emptor!!!
