While margins are low in shelf-stable grocery staples, profit on that side of the store is usually driven by volume and careful management of labor and process. Margins are also higher on private label goods, so promotional energy is spent on driving consumers to those products. At the store level, most grocery chains have started to increase their food service and perishable offerings, which traditionally have much higher (and more stable) margin which augments the profitability of any individual outlet.
