great question 🤓 - fresh foods (produce, meat, dairy, deli) are placed on the perimeter, and the corporate packaged products are in the center. the layouts of grocery stores are designed to have you shop in the aisles first with promotions, fancy end caps, and strategic marketing.

if you do your shopping around the perimeter first, you end up with a healthier cart, less packaged foods, and often it's less expensive.
