Luckily it's just DH and I, and we've been able to absorb the rising costs without dipping into savings.
For the last 5 years or so, we've gone to a different model of grocery shopping - - we go every day or two and only buy what we need. We've found it's cut way back on food waste. We prefer to eat mostly fresh food so this works well for us. We do keep some things in the freezer and pantry, but for the most part it's fresh meat, fruit, and vegetables. We meal plan around what's on sale that week. Since DH is retired and the grocery store is only about a mile from our house, it works for us.
We've always bundled up in the cold weather months and tried to keep the heat as low as possible. We're still locked in on an electric contract so our electricity costs have remained fairly stable. We have another 18 months to go on the contract. When I bought a new (to me) car three years ago I went with one that got high gas mileage, even though gas was cheaper then. I'm really glad I did that now (and didn't succumb to my desire for the Jeep Wrangler Sahara).
I really feel for the people who were living on the edge before the rising inflation.
