I had been purchasing products for last 3 years and I had purchased from most of the dealers like Flipkart, Myntra, Shopclues, and Amazon. From my experience I will say that amazon is best online marketing service. The way of dealings with customer is the greatest plus point on Amazon. Good, friendly and helpful agents. Another plus point is that faster delivery of products. I used get my products on the exact time and some times even early that the date of delivery.
