Grocery shopping seems simple—until you do it wrong. In this episode of This Doesn’t Matter, But It Should, John lays out his structured (yet slightly unhinged) approach to navigating the store with maximum efficiency. We break down his ‘Need List’ vs. ‘Don’t Need List’ system, debate what happens when a critical item is missing from the haul (panic? improvisation? pure despair?), and get completely sidetracked along the way. If you have ever felt personally victimized when running out of a kitchen staple at the worst possible time, or found yourself questioning the best grocery store strategy, this one’s for you.
