I'm not sure the exact ins-and-outs, but I do know that the program associates the person who buys through your link, permanently with you, through a sequential database identifying process. It looks at their credit card number, name, address and other identifiers and, by way of those, marks you with that person for good. There are a few other ways of getting a permanent cookie. Nothing cooler than knowing that wherever someone ends up on the `Net, they are yours. =]
I can provide you the URL if you PM me (don't want to incur the wrath of the mods)
