Make a plan to save some cash
If you're looking for some savings at the supermarket, the Arizona Farm Bureau advises having a plan. Julie Murphree says it starts with devising a menu before you get to the store.
"Once we plan and build a menu, a week's menu around that, and stick to that plan, we can avoid that impulse buying or getting something that we don't really need, which really hurts our budgets when we haven't planned ahead," Murphree said.
Another good rule is to buy fewer processed foods, becuase they're more expensive per unit than whole foods. And Murphree says you should buy in bulk when you can.
