Electrical sales rose 52% on last year, helped by demand for DVD and 14-inch TV sets. Sales of cut-price 'must-have' DVD films - this year including Shrek, Bridget Jones's Diary and Tomb Raider - were up four times, and book/newspaper sales rose 26%, boosted by Harry Potter boxed sets and Pamela Stephenson's biography of her husband Billy Connolly, each of which sold nearly 50,000 copies.
