You can avail no cost emi interest discount on SBI card on any of the merchant whether its online or offline transaction.
For Example:
Total Outstanding on Card before the purchase= Rs 10000 (non emi balance)
No Cost Emi Transaction amount: Rs 50000 deducting Rs 5000 (no cost emi interest discount)= Rs 45000
Ignore the previous emi principal which are already running. (this doesn't need to be paid)
Make the complete payment of Rs 10000+ Rs 45000= Rs 55000 instantly after doing no cost emi txn (means billed+unbilled+nocost emi txn amount) and do not use the card for next 7 days maximum. In that time frame your merchant emi request gets declined by bank as there is no outstanding on card.
But if still you want to use the card, make the payment instantly for subsequent purchases.
tested? any proof?
This trick works like Charm, I have used it when i came to know about it from @tejsngh339296
SBI is the biggest cheater so be careful, Last year we had a very big lesson during the sale for cashback card.
So they try to recover by debiting the account for the same.
So be careful regarding the sbi.
