I own a food store
. It's a natural food store
. There are about twelve different departments - from produce, organic produce, whole grains, breads, the deli, and groceries. At the end of the day I know my markups and they range from about 25% to as high in some areas as about 75%, but average about 40%. That's not a lot and it's real hard to make a living. It's hard to stay in business with the rent you're paying, the staff, the insurances, taxes, etc., but you manage to etch out a living.
