Google is testing a feature to let you get notified if there is a deal for the product(s) you are searching for directly in Google Search. It is named "Track deals from this search" and it has a slider to toggle on the notification.
The core functionality here is not new, Google had deal tracking in Chrome and other platforms for a while, but it showing up like this, seems new to me.
Here is a screenshot from Sachin Patel of this that he posted on X:
I assume Google would send you a push notification of sorts when the price goes below a certain point.
