I had been using amazon since 2014 and had placed more than 100 orders on it. Amazon’s services are best in class and very customer oriented.The delivery of product was normally 5 to 7 days before than the expected date of delivery. So Amazon gets 10/10 in the delivery speed.
The prices are also at its best. I had purchased more than 150 books from amazon and had got discount ranging from 10% to 75% with free home delivery. so its great deal if you want to purchase book. Apart from this, return and refund processes is very simple and quick with no questions asked policy.
