Yes you can see they have devalued only the swiggy offers because there is lot of competition going in with swiggy due to the new launch of HDFC Swiggy CC.
Also very online website has started to get partner with some bank and starting to issue more offers.
This might be the reason for major cards devaluation.
If you ask me , if the MYZONE card you're holding is LTF , apart from swiggy offers it has buy 1 get 1 on paytm also, you can use for that , also you get 4 RP per 200 rupees which is approx 0.4 % Reward Rate.
Also there is no harm in having a LTF card when it has atleast some movie and devalued but ok swiggy offers.
If they remove buy 1 get 1 on paytm also , then this card will be waste , i hope everyone including me 🙂 might close as without any benefits there is no use of having a card which can be kept only at our wallet as axis provides time to time LTF offers.
