Red: nice internet marketing trick!

One of the oldest tricks in the book is to list some hardware part really cheap on something like CraigsList (second hand ads), then hundreds of people email you wanting to buy it, but you email them back that it is already sold. But guess what, in the signature of your mailrespond there is a link to your site and a message for the reader to take "action" (to click on the link and visit your site) = profit.
