Cutting back on spending is the only thing I know that works. When consumers don’t buy things, the prices come down.
For groceries this means splurging less, avoiding things you don’t need (drink tea instead of soda, don’t buy snacks and chips). Fruits and vegetables are definitely still cheaper than prepared foods in many cases. Even when frozen. And they can be used to make a meal stretch, along with beans and rice.
Buy cheap bar soap and store brands of basic things.
Coupons aren’t really a thing anymore, but you can use the app for stores like the grocery, Target, Walmart, to “clip” deals and save.
A lot of the high prices right now are just greed. They aren’t tied to actual supply chain or labor issues. A grocery store in France just told PepsiCo to take a hike because their prices were so outrageous.
If you want the government to get involved, I encourage you to write your representatives about enforcing existing anti-trust laws. The mega mergers and buyouts are driving prices up because of less competition. Kroger wants to buy Albertsons for example. That just means more layoffs and higher grocery prices.
Hope this helps.
