"...but have heard that supermarket chains have very narrow profit margins, on the order of 1 or 2 cents on the dollar of gross sales."

This is the big lie they want everyone to believe. Supermarkets calculate their profit margins after paying out huge bonuses to upper management. Then they cry about their slim margins.

Kroger's most recent gross margin was reported at about 21.7% and its most recent reported net margin (in April) was 5.4%.

Historically, its net margin has varied between 5% and -5%.
