Google Search can show deals in both a product carousel format and a product grid-type of format. Some of these I think were somewhat showcased last November but over time, they may evolve.
Here is a screenshot of Google showing me deals in both a carousel format and in a product grid format:
Here are more screenshots from Khushal Bherwani on Twitter:
