Harmit Kamboe posted on Twitter a screen shot of a search result that showed rich snippet content for "promotion" deals. It is weird, this is the type of snippets you'd see for search ads but not organic un-paid results. I asked him a ton of questions and it seems like he really saw it.
Here is the snippet:
The search query that he found this for was in Toronto, Canada for [new car deals canada]. I cannot replicate it and he said it no longer comes up.
It might be Google confusing the schema or trying to be smart and showing this content, without filly understanding it is a "promotion" piece of text. Or maybe Google is intentionally trying to show this snippet as is?
I wish I could replicate it and see what is going on. The page is clearly laid out in a table format, with the words promotion as the header. Google will sometimes build these fun structured snippets based on table data, so that is my best guess here.
Forum discussion at Twitter.

@rustybrick that looks like a normal structured snippet (haven't looked deeper)
