Knock-offs, like those Coach handbags you find on Canal Street, ain’t legal. These fakers hurt the real brands—both in their credibility and in their pockets. The 'po frequently bust manufacturers and dealers, hauling in purses, glasses, jeans, etc. by the truckload. Hey, you don’t need a lecture. On the other hand, imagine a brand with the chance to fashion a positive PR opportunity out of its rip-offs. Nike, Timberland and many others swallowed their pride and did just that, making us all proud in the process.
