Prices haven’t gone up that much where I live, and some of the things that have risen in price have actually started going back down recently. But I guess it all varies from one place to another.
But in general, I shop the sales flyers, I get things that are discounted such as meat that will expire soon, and I get the cheap staples like rice and beans. I stopped buying name brand items and unnecessary snack foods. I also use the Ibotta app which gives me some cash back. Usually not a lot, but over the course of a year it’s meaningful.
