As a long time customer and admirer of Flipkart, I have no hesitation in saying that there is something massively wrong at Flipkart. Earlier FK used to be my goto destination for buying anything online, since last 1.5 years things have changed drastically.  Every single product, that i need to buy is either cheaper on Amazon India or is not available at all on FK- every single product. 
Customer service that used to be friendly is not welcoming either. On the other hand, Amazon India seems to be obsessed about customer service, they will readily offer you GV for a slightest of mistake on their part. Their product inventory is massive. Essentially Amazon india has become what FK used to be 3 years back and FK seems uninterested in doing business anymore.
