The "herbal supplement" Internet industry, which began around 2002, is still rapidly expanding, without question because it's so profitable. Now moving beyond the Internet, some of these companies also run "male enhancement" ads on late-night cable TV and in the backs of otherwise respectable magazines. Here's what these companies do: They either manufacture or buy cheap generic pills containing random herbal mixtures, and they market these pills to "cure" any of an array of conditions. The one thing all of these conditions have in common? They're all focal points of human insecurities. Topping the list is penis enlargement or "male enhancement," but as seen in Virginia's letter, there are plenty of others. (I've even seen penis enlargement pills that claim to make short people magically grow taller.) These penis enlargement pills are sold at unbelievable markups — we're talking $50 or more for a bottle of penis enlargement pills that may cost two cents each, at most, to manufacture. The profits are so large, these companies are able to offer lucrative affiliate deals to Web sites willing to advertise them. For instance, Virginia's e-mail offered that for every bottle of penis enlargement pills sold to a JackinWorld visitor, we could earn $36, and for every 4-bottle package, we'd earn $144. How could we say no to that?
