I was looking for a book. As usual with a popular book in publication I went to Amazon UK first. When I looked at the used copies I came across the following:
Used - Very Good
My immediate reaction was to wonder why anyone would offer a 30 day money back guarantee on a book which could be read and returned with ease in that time. Until it dawned on me that the guarantee will only refer to the price of the book and not to the postage. In fact in returning it one would have to pay significantly more. It looks good though!
