Hey
@ashishsinghi ,
I'm using HDFC Millennia Credit Card for more than 8months, I've we can purchase Amazon shopping vouchers, Flipkart shopping vouchers, Zomato Vouchers etc with
upfront 5% discount every time. Amazon vouchers (only 10k max limit each month) we can able to purchase the vouchers, but for this alone 18% GST will be deducted when purchasing.
Check out the "Cart summary" on the right side of the screenshot for reward value clarifications.
