Online Grocery Stores in India

Why online grocery may not be successful in India
Some time back two things happened.  I and my office colleague were having discussion on his friend opening online grocery store in Hyderabad.  Also another friend posted an quote on FB "Currently people are suffereing from MALLaria".  This got me thinking about the success of online grocery store in India and will it be ever successful in India.
