When you walk in the door, you smell bread baking or rotisserie chicken roasting in the deli area because we know those smells get your salivary glands working. When you’re salivating, you’re a much less disciplined shopper. —Paco Underhill, consumer expert and author of What Women Want: The Science of Female Shopping

We can cut a chuck roast into stew cubes, a whole boneless strip loin into New York strip steaks, or a flank steak into stir-fry strips.

That can save you about 30 percent compared with buying everything cut. —Bradley McHugh
