You pay more at the pump and grocery store because of corporate greed, not because of wars

I was watching closely for the last few weeks, prices of groceries I buy on a regular basis (sometimes multiple times a week) at my local grocery stores, there are three of them in my area, different stores with different produce, I buy some from here and some from there since some grocery stores have what the other does not have (e.g. certain branded products).

From what I see, the pricing of many price-stable products, change very radically almost on a daily basis.. now one might say "sure the prices surge!" but what if I will tell you, that I saw prices go up by more than 1-1,5 euros one day, then two days later go back to almost normal price, then again surge, then again go "on sale", then surge even more to around 2+ euros more than normal price etc..

Seem to be a long waiting at the cashiers, since most employees are busy changing price tags the entire day, and the pricing seem to be dictated by some type of higher up manager rather than common sense.

Those corporations are trying to suck us dry, it seem to me, that even products that suffered no affect from the war between Ukraine-Russia, are priced ridiculously as high of a price as a buyer would be willing to get boned with.

same with Petrol and Diesel (we have both), prices differ by 20-30 cents from pump to pump, and depends on the day of the week.. as if those who sell it try to find the "price gauging sweet spot" where they can rob us blind but still have people coming for more.

This is in western part of Europe.
