You seem to think that all that applies to you, applies to others. It doesn't. I'm happy for you if you are getting 3% CB and thrilled with Jupiter Edge CSB Rupay. But your experience with the card and other life situations need not be the same for everyone else.
For my needs, Jupiter CSB Rupay gives me hardly anything. I think Jupiter CSB Rupay is a trash card, because I'm not seeing any rewards as promised even on shopping.
As for medicines, you are wrong again. Your experience is not the norm. Discounts vary from place to place. In Mumbai I got maximum 15% discount. Where I live now, 10% is rare (nearest guy says he will give 10% but only for senior citizens; chain pharma store in a mall nearby promises 15% but rarely has meds needed and works mall hours of 10 to 9 PM). Many others are in malls too here. Worse, with all these guys, delivery happens much later and all nearby medical stores including those not in malls are shut by 10. Tata 1Mg gives me excellent discounts (can reach 20%+ when bill goes over 1K), have a massive inventory of meds where almost every brand choice is available and they ensure rapid delivery within an hour. Plus I get extra Tata Neu Points when I order on the Tata Neu Infinity.
My Tata Neu Infinity is LTF too.
The OP included Tata Neu Infinity among his choices which is why I commented based on my experience. For all you know Jupiter might pull that same queue stunt with him as with all others to create artificial scarcity. You are XXXXX in the queue, etc. Though in reality if you have a Jupiter account and your CIBIL score is good none of that matters -- you get the card within an hour or two without any number in the queue. Which was my experience and months later my wife's. Though since the card is trash now for her needs too, she simply does UPI using her Tata Neu Infinity and has blocked the Jupiter Edge CSB Rupay.
