10 Day Notification


Federal Trade Commission, 16 CFR, Part 310.2 (cc), defines Telemarketing to mean:

"a plan, program, or campaign which is conducted to induce the purchase of goods or services or a charitable contribution, by use of one or more telephones and which involves more than one interstate telephone call. The term does not include the solicitation of sales through the mailing of a catalog which: contains a written description or illustration of the goods or services offered for sale; includes the business address of the seller; includes multiple pages of written material or illustrations; and has been issued not less frequently than once a year, when the person making the solicitation does not solicit customers by telephone but only receives calls initiated by customers in response to the catalog and during those calls takes orders only without further solicitation. For purposes of the previous sentence, the term ‘‘further solicitation’’ does not include providing the customer with information about, or attempting to sell, any other item included in the same catalog which prompted the customer’s call or in a substantially similar catalog."
