I'm yet to see prices going down, or at least not going up at the same pace as everywhere else, because a supermarket chain implemented self-checkout.

I don't think anyone buys (pun intended) the argument of self-checkout being there to enable lower prices for consumers.

Around where I live, Market Basket AFAIK has no self-checkout and probably the cheapest prices of any of the local chains.

Given the extreme inflation, most likely it means priced did not increase as fast as they otherwise would have.

If consumers did not like them, they would not use them and the companies would get rid of them. Unfortunately for you many consumers not only are willing to use them some even prefer them because they in fact do not want to interact with a cashier
