I don't spend much anyway, so there isn't much to cut back on, except at the very margins.
Several years ago, I switched to buying exclusively Ground Chuck for chopped meat. Before, I sometimes bought the more expensive types of that. Even today, it's rarely below $5 per pound. More recently, I stopped buying the more expensive organic brown rice, sometimes from health food stores before it became more readily available from the local supermarket. A 2-pound bag cost $8 but I recently found a 5-pound bag on sale for $4. When I finish that big bag, I expect to pay something between those 2 prices per pound.
My favorite junk snack foods, potato chips and pretzels, have risen a lot in price the last few years, even pre-covid. I had been able to find the chips for $4 per pound. But nowadays, it's nearly impossible to find it that cheap. Only if it's on sale, and really marked down. Often, those $7-per-pound bags get marked down......to $6! I mutter to myself, "That's NO bargain!" Pretzels are hardly better but are more often available for $4 per pound. If I can find either below $4.50 per pound these days, I may get them.
Boneless chicken breasts used to be on sale more often, anything below $3.50 per pound was good. These days, I'm happy to find it at $4.50 per pound.
My ladyfriend seems to find bargains for my snacks and chicken at Aldi's (and milk, amazingly, for $2 per gallon, less than half what I pay at my store), so she gets some for me. It is such a PITA to get there and deal with the awful parking and crowds that I can't bother with that, even on weekdays at 10:30 AM. I have to drive her around, so on her monthly shopping sprees there I have to deal with that awful parking lot - twice!
