It means that if a customer who has been cookied through one of your affiliate links returns to the site you referred them to without tripping another cookie along the way and buys something else you get the commission - this is unlimited within the cookie period.
I believe he means that as long as the person doesn't click on another referal to the same service after clicking on yours, you get paid. In other words, if fred customer clicks on your referal to widget.com and buys a widget, and then clicks on my referal to widget.com and buys another, we get 1 commission each. However if he clicks on your referal to widget.com, buys one and then later goes to widget.com directly and buys another you get commision on both sales.
Thank Yall so much. I am very much a green horn in all of this, but a very much excited green horn. My goal is to eventually earn enough money to replace my second job ($800 a month) I hope it doesn't take more than 6 months to accomplish this.
Again...thank you so much. I have another question for you two, but I will start a new thread to post...watch for it.
