Beer and Diapers.
What does that say to you? You don’t think the two go together? You do?
Or you know the story that a huge US superstore was claimed to have used data analysis on shopping trends to decide on their product placement in store — famously putting the beers on a special offer price just adjacent to the diapers? Obviously the target customer is the dad with a small baby, rushing in to get diapers — probably tired, had a hard day… whatever. He spots the beers on offer by the diapers and he’s going to get them.
