Compare unit pricing. The biggest package isn’t always the most cost-effective. Stores know that consumers want to buy in bulk, and so they mix it up: sometimes the bulk item is cheaper, sometimes it’s more expensive. The only way you can be sure is to take a calculator.

Don’t examine things you don’t need. The more you interact with something, the more likely you are to buy it, says Paco Underhill in Why We Buy: “Virtually all unplanned purchases…come as a result of the shopper seeing, touching, smelling, or tasting something that promises pleasure, if not total fulfillment.” Do you know why grocery stores place those displays in the aisles? To intentionally block traffic. They want to force you to stop, if only for a moment. It only takes a few seconds of idly staring at the Chips Ahoy! to convince you to buy them. Stay focused.
