WSJ.com - 'Harry Potter' Lifts Sales, But Borders Net Dives 84%: "Sales of 'Harry Potter and the Half-Blood Prince' accounted for about 4% of the 6% rise in trade-book sales. Sales of the book went 'as expected,' with sales having an initial burst when the book first came out and then slowing quite a bit since then, said Borders finance chief Ed Wilhelm. He attributed the slowing to more copies of the book being printed than previous Harry Potter books, with the latest being more widely distributed than past installments. However, the top 50 books excluding the Harry Potter book were down from the a year earlier.
Consumers who purchased the new Harry Potter book also spent money in the retailer's cafe, and other children's-related products sold well because of the book, Mr. Wilhelm said."
