flipkart is one of most leading online shopping website for Indians. I used to purchase products from Flipkart. Last time I purchased was around 6 months back, Today when I tried to purchase few things it displayed that
Sorry, the following items cannot be delivered to the address provided, since Flipkart service is not available in your location.
I called the flipkart customer center and the reply I received is that , Flipkart is no more supporting third party courier services and depending only on their own courier service, and it won’t deliver on your locations.
So no more Flipkart Purchases for me 
So before you try to purchase a product from flipkart just check with your pincode to know whether Flipkart service is available at your area.
Update
Recently Flipkart stopped delivering to Kerala. One of my friend who ordered a Moto X which is only available via Flipkart. He placed the order with a Kochi address, but next day flipkart cancelled the order. Now flipkart is not adelivering to any Kerala Pin codes.
As the Micromax Canvas Win W121 spotted at Flipkart, which we plan to purchase, just wondering what people from Kerala can do to get the product.
