How did you redeem points for CSR? We used to be able to book Disney hotels with Chase Ultimate Reward points but of course, they had to stop that. I don't know why they care if they get paid by us or by Chase. Either way they get paid.
Go to the rewards portal and choose "Pay Yourself Back." You can redeem points for dining, gas or grocery purchases going back 90 days. The redemption value is 1.5x points, so as an example 50,000 points would get you a $750 credit. It's instantaneous and gets applied as a credit to your account. Do this until April 30 for the bonus 1.5x redemption. After this, it will be 1x cash back like it used to be. I've been doing it every month since September.
