Most of people miss that Amazon ICICI card comes handy to purchase high priced items such as Mobile Phones, Laptops, Home Appliances etc... as for normal cards there will capping on max discount per card, like 1000, 1250, 1750 during sale.
But if you are purchasing something worth say 30k & above, then the 5% on Amazon card, beats any other offer with capping.
On a purchase of 50k, you can get 2.5k discount in Amazon pay balance.
