One other measure of relief concerns the purchase of supplies. Marketing is a science and might be made a profession. At present it is usually done in a haphazard, make-shift fashion. It is done by the head of the household on his way to business and thus done in haste; or orders are given through a clerk who goes from house to house and thus serves primarily the firm he represents, while at the same time the purchaser loses the benefit of competition in the markets; or commissions are given by telephone and the customer has no opportunity of inspecting the goods before purchase; or marketing is done by the mistress of the household, who is unable to reach the markets in time to make her purchases with the care that should be given; or it is done by the cook, who may know the best articles to purchase but is ignorant of their money value. It requires time, skill, and experience to purchase judiciously the supplies for a household, and in many households time, skill, and experience are lacking. It would seem possible for one person to do the marketing for fifteen or twenty families, taking the orders at night and executing them in the morning. Supplies could then be purchased in quantity, this gain would pay the commission of the purchaser, and marketing would be done in a much more satisfactory manner than it is at the present time. At the same time such a plan would relieve the members of individual households of the burden and care of a difficult part of household management.
