I think it's less "gone crazy" than before - like if you compare it to 2022/2023, things have calmed down a bit on certain stuff. But yeah, you're right that it still feels heavy, especially on basics and budget items. It's just that brands are reluctant to lower prices even when their costs go down, so we're stuck at high levels.
For tips that actually work, the thing is don't just rely on the base price - check the price per kilo or per liter, that's your friend. Small budget packaging is often a trap, you end up paying more. Then store brands vary hugely from one chain to another, so if you've got another shop nearby, it's worth comparing just on the stuff you buy regularly. And promos, even if they're less generous than before, there are still some around - you just gotta check before you go shopping.
