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.
I like Russell Watson and when I order The Ultimate Collection I though I was getting his CD. Unfortunately, I received the CD cover with a CD from Roxette Look Sharp by EMI made in Holland. This was not the CD I order and when I finally got to listen to what I though was the CD I order it was too late to return the CD for an exchange according to AMAZON's return policy. Morale of this story is to review your orders as soon as you get them in order to return products that are not what you ordered.
