You can get Bob's Red Mill muesli in 25 lb. sacs. for $50, or $2/lb., which is $4.4 per kilogram. Figuring 4 calories per gram, the daily caloric equivalent of 2300 calories is met for $2.53.
Even bulk purchase cereal alternatives, such as Cheerios , are much more expensive and any cereal from the grocery store is many times more expensive. Meusli, unlike cereal, doesn't go stale. It can serve therefore as emergency food, even more so as it doesn't require cooking to be palatable. With milk, fruit, yogurt added there is much variety in taste, so no need to get tired of it. Unlike processed cereals, it is broken down more slowly, and thus is a carbohydrate with a low glycemic index. It is fantastic in bread (see bread machine post above).
