Hey folks, I'm new to the game, so excuse the excitement on this one. I have been using HDFC Infinia Smartbuy to book over 50 train reservations over the past year. I used Smartbuy because of the 3X multiplier, bringing the total rewards to ~10%. But I just noticed that if I book directly using IRCTC and pay using the Amazon Pay Gift balance (Amazon Gift card purchased from Gyftr using Smartbuy), we can save up to 14% (16%-1.8% processing). Am I just too busy to not have noticed this before? or does this surprise you as well?
