Either use Flipkart through Axis Grabdeals and get an additional cashback, or see if Croma can deliver at your location, and if the price is same, buy it through Tata Neu, using the Infinity and get an additional 5 % up to 750. If you are a very regular user of Flipkart, then buy the VIP membership. Can give you another 200 Supercoins, that you can spend on the next Flipkart spend, on a 5 percent basis. But they've increased the VIP price, and reduced the supercoin validity, so only go for this option in case you use Flipkart regularly.
