BBC NEWS | Business | HMV makes move on Ottakar's chain
Last month, Ottakar's warned same-store sales dropped 6.7% in the 4 weeks to 16 July - blaming the Harry Potter phenomenon for the drop. The group said that customers had opted for reduced price copies of Harry Potter and the Half Blood Prince available at supermarkets such as Tesco and Sainsbury's. It also said the release had prompted many publishers to delay the launch of new titles as they feared harsh competition from the children's book.
