See, ebooks at Amazon cost in the range of $6 to $9 for most of the fiction books. Sometimes, there are bargains/discounts and sometimes, they give you a book for free even (if you keep an eye on it of course). Prices of Physical books in India depend on where you get them from. For example, a John Grisham latest would cost about 400 at landmark/flipkart, and the ebook version would be about $9. In US, there is a lot of difference in pricces of physical and ebooks. I have seen some physical books costing about $25 and the same ebook would cost $9, both at Amazon. In india, however, the situation is different.
