I require an almost no sodium diet. Plus I like organic food and things without preservatives. When I lived alone, in Jersey I would spend about $140-$170 a month on groceries. Which works out to $35-$42.50 a week on groceries.
Now that I am in a house with 3 adults and special dietary requirements. We have one diabetic, two with high blood pressure and me. I guess we spend about $200-$300 on groceries a month.
