To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Major problems. Received a book clean and looking fairly new but clearly no-one at the Store has opened it. On turning each page, it comes loose. So I have a"book" consisting of some 200 pages of loose pages!!! Would have returned it but needed it immediately for my book group. Have never before had a problem with the used book option: till now consistently good. Content of the book - as hoped - magical writing!
