I don’t know if there is or not. My old card expired and I haven’t gotten a new one. Sounds like others haven’t as well.
But, you can see below in the CC benefits link that says it is a benefit (but maybe not updated). Don’t know.
Also, last year it was 25% off. They eliminated the discount using a ticket stub (I think that was 20%) and upped the percentage from 20% off to 25% off using the card.
Sad if it is no longer available. I really liked that benefit. I definitely purchased more than I otherwise would have, for me, and others.
