Well, the originators of the ClIf Bar sold the company in 2022. You think that may have something to do with it?
There is a link to a response from a consumer to the new company that basically stated that their research showed customers would prefer a smaller bar vs. paying more. So yeah, they've gotten smaller. (But I'm not buying the so-called 'research' one bit.) Of course, I can't post the link. Do one of those fancy computer searches.
