A signed first edition of Harry Potter and the Half-Blood Prince has been sold for more than £500.
The book was bought on Saturday in Edinburgh, and was signed by author JK Rowling, and was then put up for auction on the internet.
At the end of the sale 23 bids had been made on it, with it finally being sold for £512.66 on Tuesday morning.
In the UK more than two million copies of the Half-Blood Prince were sold in the first 24 hours that it was on sale.
And fans in the US were also keen to get their hands on the book, buying 6.9m copies in the first day of sale there.
But there have been problems in India, with fake copies on sale in street markets in Mumbai (Bombay)
Illegal copies of the book were on sale just two days after the book was released, and cost almost a quarter of the price of the official versions.
The Half-Blood Prince - the sixth in the series - came out in the UK at midnight on Friday.
JK Rowling has told fans the seventh and final instalment of the Harry Potter books could be out in about two years' time.
She was talking at a press conference in Edinburgh, where all the reporters were children aged between eight and 16.
After the press conference, 14-year-old competition winner Owen Jones, from Cardiff, quizzed JK in the only main interview she will give during the Half-Blood Prince's release.
"I think I give very clear pointers as to what Harry will do next," she said of book six.
"There is plenty to guess at... at least one thing I think people will probably deduce, there is a mystery left at the end, but I think they might already know the answer if they think about it."
