Supermarkets have a very low moral compass

It angers me that they continue to gouge the public.
Looking at the profits over the previous four years it has remained the same, right through.
More than a billion dollars each year.
So while the public is suffering, the supermarkets are maintaining their profit margins.
Not hurting one little bit.
An item not available to make a profit on? easy, raise the price of other items.
Shame on them.
