Key stat: Half (50%) of US adults said they didn't notice any offers during their most recent restaurant purchase, compared with 46% in retail and 32% in groceries, according to a March 2026 PYMNTS Intelligence study conducted by FIS. Beyond the chart: The awareness gap isn't that diners don't care about deals, it's a channel problem. Some 33% of US restaurant diners discover promotions via email or newsletters and 32% via social media, according to a YouGov survey.
