James 'has outsold Potter' on Amazon UK

E L James Fifty Shades trilogy has out-sold J K Rowling’s seven-book Harry Potter series on Amazon in the UK, the online retailer has announced.
Although James’ erotica books have only been on sale since March 2012, they have sold over four million copies in print and digital, making James the bestselling author ever on Amazon in the UK.
Rowling’s final book in the Harry Potter series, Harry Potter and the Deathly Hallows, is being outsold by the first book in the James trilogy, Fifty Shades of Grey, by more than two to one.
Gordon Willoughby, EU director of Kindle, said: “In just four months, EL James has become Amazon.co.uk’s biggest selling author of all time which is truly remarkable when you consider that we’ve been selling books for almost 14 years.”
