The same quality and quantity? Yes. Otherwise people wouldn't have had a thread talking about WIC products and no name brand cereals.
You're trying to tell me when you get rich you're going to change your diet to trader joes?
I don't know about you, but I'm not, I'm just going to eat the same foods but better quality and various amounts, and eat at way more expensive restaurants. My beefs and steaks will be cut from much more expensive grocery stores/butch shops. My toppings and spices will increase. Instead of buying low or mid tier products on the shelf, I'm going to be getting the top tier, a nikka going to be sprinkling truffles on his pasta my nikka.
