Query: Distinguish book alone version, sold without audio or cds

People should understand this book is sold in a version without any audio/cds. You then have to buy separately one of two companion audio/cd programs, which the book references. Without audio of any kind, the book alone is useless unless you aren't a beginner. As long as you understand that, great. I mail ordered this sight unseen based on the Amazon reviews (but from a different vendor). When it came as a stand alone book I returned it because the cd version was cheaper than buying the book and the program counterpart separately.
