After reading this thread I checked a CCBill program that i had just added new links and content to. Literally, this was the last CCBill site I linked to before reading this post.
Clicking my CCBill link (on my website) and arriving at their tour, I clicked on their join page link and got this page:
www.***************.com/tour/join.php. Clicking the "Join Now By Credit Card" link, I'm directed to
https://bill.ccbill.com/jpost/signup.cgi
Typing the website's url without my affiliate code lands me at (after clicking the "Join Now" link):
http://www.***************.com/join.php. Subtle difference.
Clicking the "Join Now By Credit Card" link, I'm directed to:
https://bill.ccbill.com/jpost/billingCascade.cgi
I'm gonna guess that my cookie gets carried over to the different join form, but its easier for me to delete the links than it is to check my cookies.
