Flipkart is one of the main reasons online shopping has become prevalent in India, but after becoming a marketplace they have messed up a bit (experiences of some friends and http://www.thinkdigit.com/Internet/Flipkart-screwed-me-over-... for example). If they manage to get the trust back, they have a great future, if not they will soon be unable to differentiate themselves from the other sites that are so rapidly cropping up.
