Bro, the sum insured is divided by 12, so your sum insured could be an issue. First, check with Croma or Vijay Sales, or if you’ve used this method in the past, verify the invoice value. I know it might reflect the same value, but I’m not convinced this method would give you any cashback—60% or even less—because it’s based on the sum insured that’s swiped on the machine.
Also, you might not get anything because of the gift vouchers (GV) bought from SmartBuy. So, check with Croma, Vijay Sales, or any Apple third-party seller that offers GVs to get an idea. I know they might say it won’t work because they’re not informed, but try checking on YouTube or Twitter to see if someone has used this route for better clarity
