Google Search has a carousel, which may or may not be new, that shows categories of offers from a merchant as part of the overall snippet. The carousel is beneath the main snippet and sitelinks (if available) and shows a scrollable carousel of offer categories.
I spotted this via Punit on Twitter and I am able to replicate it, here is a GIF of it in action:

I do not yet see these showing on desktop search, just the mobile results. I do wonder if this comes from the enhancements Google announced last June around promotions and deals in search for merchants or if it is more of a local offers attribute integration - or maybe something else? I do suspect it is signed to Google Merchant Center data.
