Many households have one. Open a kitchen cabinet or utility drawer, and you'll often find a large shopping bag filled with dozens of smaller bags waiting to be reused. Some people laugh at the habit. Others assume it reflects extreme frugality. Psychology, however, suggests that regularly saving shopping bags says very little about whether someone is "cheap." Instead, the behavior is often linked to planning, habit, environmental awareness, and a tendency to avoid unnecessary waste.
Of course, there are practical reasons too. Reused bags can help carry groceries, line small trash bins, pack lunches, store items, or transport wet clothes after a workout. Rather than revealing one personality trait, the habit often reflects how people think about resources and future needs.
