This is the TWENTIETH YEAR that I have been in the subscription business, and in this Catalogue No. 39, I am giving the best bargains in periodical literature that have ever been placed before the public. In order to enable me to do this the publishers of these periodicals have sacrificed their prices until in a great many cases they do not obtain from the subscribers to these club offers the actual cost of the white paper on which they print the numbers that they will mail to fill the year's subscriptions. They have done this to introduce their periodicals to the largest number of readers possible, believing it better to give the subscriber the benefit of the price than to spend the thousands of dollars in advertising, which would be necessary to secure the same number of subscriptions and the same amount of publicity. This catalogue will be sent to a number of hundred thousand persons besides the tens of thousands of my regular customers, a large number of whom have sent me orders regularly for years. My close relations with publishers, my immense business, my unequalled facilities for handling orders, my long experience in this work, my thousands of satisfied customers located in all parts of the United States and Canada and in nearly every civilized country of the world all combined guarantee that all dealings with me will be satisfactory. My motto has always been that a satisfied customer was my best advertisement. On account of these things, publishers give me the lowest possible prices on periodicals, and I guarantee to my customers that my prices to them are the lowest obtainable. I hope to receive the orders, whether they be large or small, of all my old customers and also of all others who receive this Catalogue, and hereby promise to give the same my most careful and immediate attention. Hoping that I may serve you in this matter, I remain, Very truly yours, D. D. COTTRELL. Offer No. 4. Any one in Offer No. 4 may be substituted for any one in Class A by adding 25 cents to the club price for each one so substituted.
