I finally made a purchase on the McDodo website. I didn't quite get responses to queries over email, so I am not sure how good their warranty service will be. May be they will respond over the phone, but at least it is better than purchasing seller warranty products on Amazon.
Also, the automated 2% coupon provided on chat didn't work on account of too many usages. However, keeping the item in the cart resulted in receiving a 5% off coupon a few days later.
Item was shipped from Ahmedabad using Bluedart. But they used surface shipping, so it took 4 days to arrive.
