They fixed the price of bread for years. Before getting caught, if people had asked them, "are you fixing the price of bread?", they would have said No, and probably have acted insulted that they were even asked.
So now, if we ask them if they're fixing any other prices, they'll say No, and act insulted.
After last time, why should we believe anything they say at any point?
Not sure about elsewhere , but our local PC changed bread recipe right around the discovery of fixed pricing. Their in store bread went from really tasty and textured , to a bland fluff loaf worse than wonderbread. They might have thought if we can't overcharge we will just tank the quality of flour used
