Buying food for the whole week is much easier – and cheaper – if you’re going to cook.
That’s because you’re likely to buy food, as opposed to ‘not food’ or ‘might not be food’.
Examples of ‘food’ are: a whole chicken, a bag of carrots, celery & onions (not yet chopped), a bunch of spinach, and a bag of potatoes.
Notice how the only ingredients in all of the above are also the same as the actual list of foods.
It’s much easier to get lost, confused, and overspend in the central aisles of your supermarket. Coincidentally, much of what you’ll find there is not in the ‘food’ category, and, it’s not filling either.
Which is why you have to buy more of it.
