The adage that the more you do something, the better you get at it doesn't just apply to mental focus or running a mile. Food shopping, too, is a skill, and when you practice it, you start to learn how much different foods cost and can spot true deals. So, consider divvying up other household duties but
designating one person to be the official grocery shopper. That way, she or he will be able to develop the skills needed to be a better shopper (
and not just to remember the price of these four items).
