My wife and I have two totally different approaches to food shopping. I make a list, go in and get what’s on the list, and am out of the coop in no more than 15 minutes.
She has a list, too. But then she looks at what else is on the shelves. She compares products. She seeks out new products. She asks when something is not on the shelves. She consults with the staff about products and their alternatives.
She shops as if she were in a hardware store!
