Book excerpt: With the sky-high price of advertising and direct marketing, only Fortune 500 companies can afford to promote their products and services through traditional channels. Add to this problem the greening, graying, and huge youth markets that have learned to turn off Madison Avenue-style promotions, and the vast majority of small to mid-sized companies, entrepreneurs, and overworked marketing staffs are challenged to expand their customer base in other ways. That's why "guerrilla," aka "unconventional marketing," was born. The Complete Idiot's Guide to Guerrilla Marketing, written by marketing experts Susan Drake and Colleen Wells, presents a detailed blueprint of the dozens of new and exciting methods available-methods that save money and get new customers.
