Cherry-pickers get better with experience. A family that cherry-picks on 4.3 percent of its grocery runs, the median frequency, averages $11.93 in savings per cherry-picking trip. But families that cherry-pick 20 percent of the time save an average of $15.76.
Professor Fox said that few academics knew about cherry-picking, but that he found that grocers were well aware of them — and, he noted, "they hate them."
