I had a look on the whole foods website and found a store in NYC. you can buy 1lb mince, spaghetti, tinned tomatoes, carrot onion garlic, for less than $12. that's a meal for 4. you can get rolled oats for about $.75 a portion with real milk and a half a banana, and as a lunch you can get bread, pastrami, cheese for <$15, for about 8 sandwiches. that's $6/person/day from whole foods in NYC not buying in family quantities.
