I am purchasing materials around 3 yrs and I have buy things from many e stores but I thing the best one is flipkart. Not just for a huge available product range but also quick delivery, Quality of product is make them front linear. WS retails is the best vendor of flipkart as it takes minimum time for delivery, takes care of your product and deliver the best thing to you.
I had buy my phone from flipkart and it delivered within 3 days. It is also very easy and simle to return the products. I can give full marks to this e-store.
