You don't need an SUV to drive to the grocery store and bring home a week's worth of rations when you live or work close enough to the grocery that you can walk there to buy groceries for each meal. Get a bit of exercise. And get fresher food.
You don't need a super-center or mega-grocery to buy the ingredients of an excellent meal. Here's a grocery two blocks from my office that only has 4,500 square feet of sales space.
