One person drinking two galons of sugared milk over a week is absurd. Similarly, a single small grocery cake should take one person a few days to eat and will go stale, even in the refrigerator, in less than a week, unless it's boxed factory cake with poisonous levels of preservatives. Cookies are hardier, but there is no point in buying 6 packs of cookies unless they are on sale. Since you'll be going back for groceries every two weeks or so and a single pack of twelve should last one person like a month.
