I have these cards with me, but i am unsure which card gives maximum benefit for shopping offline. Please suggest one card among these: 1)Apay ICICI
2)Kotak League
3)Tata Neu Plus
4)SBI Cashback
5)ICICI Coral
6)HDFC Millenia
7) SBI simplysave
Also which cards do you think should I apply to maximize my offline cashback?
