“Plan the order of your stops in a clockwise direction,” advises Susan Hamersky, owner of the Los Angeles– based errand company California Concierge. “That way, you avoid all the time-consuming left turns.” Also, schedule your errands so you can drop things off (say, your dry cleaning and film for developing) on your way out and pick them up on your way home, says Dan McMackin, a spokesman for UPS and a former driver. Keep a cooler in your car for perishables, too. Then a stop at the market doesn’t have to be immediately followed by a run home to the refrigerator, says Julie Hagenmaier, founder and CEO of My Girl Friday, an errand company in Cincinnati.
