I have ordered a book from Amazon.in on 4 February 2017. But the product is not delivered yet. I thought it will be delivered within 4 days and not got the product. I also ordered book on Steve Job’s life, it delivered around 11 days after ordering this book, also the paper quality is not good. Delivery time is very bad. Refund policy is not guaranteed. Return policy is also not guaranteed. I think Amazon is worst for books.
