Sign up for grocery-store loyalty cards. It takes only a couple of minutes. Then, even if you forget your card, you usually can get the discount prices on that week’s sale items by simply giving your phone number at checkout. Don’t want to carry around all your loyalty, rewards and membership cards? You can consolidate them all on your smartphone with the CardStar app (free; Android, Apple).
Play favorites. If you frequent a grocery store such as Kroger, Publix, Stop and Shop or Target often enough, it might start mailing you coupons for the products you buy most. This is one of the best ways to nab coupons for fresh meat and produce.
Access discounts. Many chains designate one day a month for seniors or members of the military to receive extra discounts. If you or a family member fits the criteria, go for it.
