I have about 2,000 books on Amazon. Every time I press the Sellermania button it breaks my heart to read " Reduced in price 60; Increased in price 10". But, in fact, the system reduces my cheaper books by a few pence and gets them out of the way. At the same time it increases my better books by a few pounds and secures me excellent sales that I would otherwise miss. It seems to me that Sellermania is worthwhile if your average book sells above £10.
