@kentindell my data can not on its own. However, for basic groceries, i.e. milk, specific meats, some fruits, another governmental org recently released the prices the grocery chains pay the producers. In that case, it's the stores that did the gouging.
We do observe stagnant/decreased year-over-year profits for grocery chains in Austria as well. But there's a big but :)
You see, their operating expanses have not increased dramatically. What has increased are their "investments".
