Nokia India has no online store to enable you to buy devices online and because of that for a long time the Nokia India website has just listed the devices and their specifications without mentioning the price. That has thankfully changed, now you are presented with the devices along with their respective prices so it is easier to plan your next buy and compare phones.
The one thing that I have noticed that the prices displayed are more than what you will be quoted at your local Nokia Priority Dealer. If you are looking for exact rates, another retailer The Mobile Store has pretty accurate prices on their website.
I hope Nokia India takes this seriously and updates the price list often.
