Flipkart is an already successful startup which is into selling books, games, movie CDs and mobile phones. Books market remain their primary target. Flipkart has done it well: it has a nice interface, huge collection, good SEO/SEM and most important of all they have managed to crack the timely delivery problem really well. Nothing kills a business more than delivery/logistics problems. Customers hate to wait once they have paid. They also have a pay only when you receive model!

Flipkart is going to 1. either be acquired by Amazon or 2. become really big in Indian market
