Maybe J.K. Rowling doesn't have enough money. After writing seven Harry Potter books, which spawned the most successful movie franchise of all time, Rowling is now offering digital versions of the novel at the Pottermore Shop. The e-books, which range in price from $7.99 to $9.99, are expected to sell like crazy. They are currently available in English, but Spanish, French, Italian and German translations will be available soon. Rowling retains the digital rights to the Potter series.
