38 THE MODEL STOCK PLAN each of which must be regarded as a separate class. In the lowest price range come inexpensive cotton house dresses, rayon, and the cheaper grade of silk dresses, with three full- line prices of about $2, $6, and $9. Just above this comes a class comprising medium-priced dresses at about $11, $17, and $23. In the next class are the better grade of dresses at about $29.50, $39.50, and $50.00. At each of these prices the buyer will plan to have in stock a full line. If be has a full line of silk dresses at $35, he has in that full line taffeta, silk, canton crepe silk, and dresses of any other silk materials in demand which a customer can expect to get for $35. Then he works out the different materials in all the styles desired; and he plans them accord- ing to the six classifications listed in the next paragraph. The buyer must satisfy all of these diverse wants at the $35 price. When he has done it, he has a full line of merchandise. He does the same sort of planning for each of his other full lines. He cannot profitably keep such really complete assort- ments at too many prices. He usually keeps such a complete assortment at no price. One of the greatest advantages of the Model Stock Plan is that ke can profitably keep a complete assortment ai the three full-line prices. A full line consists of six definite classifications. If all six are properly maintained, we are assured an assortment of goods that fits almost precisely what almost all customers are looking for. The six classifications are: I. Staples. 2. Style merchandise. 3. Novelties, 4. Outsizes (for stocks that have a size element). 5. A BB (Best Buy). 6. An MP (More-Profit Item). Staples are, as we know, the class of goods commonly in demand, often year after year. Their place in a full line is obvious. ! Even above these come the de luxe goods, the handling of which is treated in Chap. V, p. 68.
