I was looking at buying "The girl with the dragon tattoo" by Stieg Larsson so I had a look on iBooks and it's Â£6.49. I then looked on the kindle app and saw the exact same book is Â£2.70!!! That's a difference of Â£3.79! Why are the books on iBooks so expensive. I do think that the free books are good and I don't think kindle do free downloads.
