WS Retail is the best seller available in Flipkart.com
It is a part of flipkart.com only and provides a very good service to customers. I actually use to prefer there products only. The return and exchange is very fast as compared to the the other sellers in Flipkart. Flipkart is only running because of them. You can buy blindly from them, if you see seller WS Retails, just buy it. The also deliver the product in less than 4 days.
