Cash tills ring to the tune of Harry Potter

By Mike Collett-White

LONDON (Reuters) - Cash tills around the world rang to the tune of Harry Potter over the weekend and the seventh and final book in the boy wizard series looked on course to become the fastest selling book ever.

Author J.K. Rowling already boasts the record with the sixth installment, and early sales figures from British and American retailers suggest "Harry Potter and the Deathly Hallows" will eclipse it.

The Asda supermarket chain has been selling the hardback at a heavy loss, charging five pounds ($10) for the 608-page volume, a fraction of the recommended retail price of 17.99 pounds.

The heavy discount paid off in terms of volume, with the store selling 97 percent of its 500,000 copies within about 36 hours of the book's release. More copies have been ordered.

"The nation really has gone Potter potty," said spokesman Ed Watson, who added that "Deathly Hallows" sold twice as quickly as "Harry Potter and the Half-Blood Prince," published in 2005.

A spokeswoman at Bloomsbury, Potter's British publisher, was quoted by the Observer newspaper as saying British sales of the final installment could reach three million copies in the first 24 hours, up from two million with "Half-Blood Prince."

Borders Group Inc. (BGP.N: Quote, Profile, Research, Stock Buzz), the second-largest U.S. bookseller, said it sold about 1.2 million copies in the first day at its 1,200 Borders and Waldenbooks stores globally compared to 850,000 copies of the sixth Potter book in its first day.

"This is the highest single-day sales of any title ever in Borders history," the retailer said in a statement, adding that about 800,000 Potter fans attended celebrations in its U.S. stories in the countdown to the book's release, many in costumes.
