Flipkart is India's largest e-commerce company with a vision to become the 'Amazon of India'. It has grown rapidly since its founding in 2007 and now has over 1 billion annual sales. However, it faces increasing competition from Amazon and Snapdeal. While Flipkart's big sales like Big Billion Day are very popular, they have also been plagued by issues like site crashes, fake discounts, and logistics problems. To sustain its leadership, Flipkart will need to address these operational challenges and develop more unique products and services to retain customers.
