I have a direct sales MLM gig. ((Tried to add fake url to show the general long url structure here)) Who is going to type all of that? So, I bought a domain name and forwarded it directly to my rep sign up page. No masking, just forwarding. I am getting messages that the "add to cart" link to complete the free rep process doesn't work. Is there a way for the company to stop the checkout process if the referral comes in from a different url??
