I purchased the Stieg Larsson thriller The Girl Who Played with Fire on February 12th for $5.00. Now it is on sale for $7.99, a noticeable price appreciation. Is it the effect of Random House books appearing in the iBooks store? In my opinion, e-Books should be cheaper. They are cheaper to replicate and distribute. They cannot be easily shared with anyone else, which in theory should lead to more individual purchases.
