With no significant competition to Flipkart in the near future, they are fully enjoying their monopoly in the world of eCommerce. In the latest they have raised the price limit for free shipping to Rs. 300 which means you have to pay Rs. 30 in case if the total order amount is below Rs. 300.
It may not be a big issue for those who usually order above Rs. 300 but it may be a big issue for those who order cheaper things like novels or fiction books.
