There was a study in Denmark that showed 25% of the income from sales in supermarkets went into advertising.

It is interesting that the distribution, not production, dominated the prices since ancient times. 2500 yeas ago in Mediterranean transporting wheat 100 km over land doubled its price compared with price at a sea port which was already quite higher than production. In a bad year when local crop failed rich citizens prevented widespread hunger by buying enough extra bread overseas.
