SBI’s association with GYFTR has been long pending.
Using SBI credit cards you can buy the vouchers with "instant discounts".
The link to the offer is here.
https://www.sbicard.com/sbi-card-en/assets/docs/html/personal/offers/vouchers/index.html
The validity of this link is from 23rd September to 27th September.
But I think, SBI is testing it out and I guess that they are planning to make it a permanent feature.
In the screen shot image, you can see that you get 3% instant discount on amazon vouchers.
The maximum Amazon vouchers that can be bought is Rs 20000.
You will get reward points additionally over the discount. For SBI Prime Reward points worth 0.5% will be given. For SBI Simplyclick 1.25% worth points will be given which takes the total savings total to 4.25%.

Comparison with HDFC’s Smartbuy.
| SBI GYFTR Offer | HDFC Smartbuy voucher |
Duration | 23rd-27th September | All year round |
Offer | 3% instant discount | 5% cash back after 3 months |

I have maxed out this offer as I have a schedule Insurance premium coming up. Also I don't hold an HDFC credit card presently!
