OK, I realise that I'm sticking my neck out by disagreeing with most of the reviews here, but I was disappointed with this book.
That said, if you are a complete beginner to ebay and only intend to make a small amount of money from it, then it's probably for you - it covers all the basics in detail.
My main disappointment though is that it all seems rather obvious - anyone who has sold 2 or 3 items will know 90% of what is in this book.
A final point - do not buy this book if you intend to make a living, or a significant income, from ebay. Even in the introduction, where the author should be grabbing the reader's attention, he points out that a busy day nets him about £100 - before tax. Hardly a fortune. The fact that he considers this a good day, and moots taking the next day off because of it, does not speak of a man with ambition.
If you want some basic advice on selling low-value items and are new to ebay, then this book probably gives good advice. If your sights are set higher, don't bother.
