Yeah we know that amazon is world’s best and incredible site for online shopping but the only thing I don’t like about amazon is that it’s late delivery time, my uncle has his RBI exam on 27 November or 28 November so he needed an RBI book for preparation so he want to amazon site and saw a book and he decided to buy and when he saw that it will take 4 to 7 days, he bacame anger and said that he hates this and cancelled, but I told him to buy and told that no worry it will not take much time to deliver how much it’s showing to us, then he became happy. So I hope amazon will improve this and will not take longer time to deliver products
