Only one problem, it had an exit pop-up which is incentivized to grab the visitors email address. This is a big no-no, so I contacted the vendor and asked if it was possible to get a custom link without the exit pop-up.
This was the response I got the same day..
"Since all of our technical aspects of our site, as well as our Sales & Marketing are outsourced, I will have to find out about your first question (i.e., removing the exit pop ups). We have several thousand affiliates and to my knowledge, no one has asked that question before, so I am unsure of the answer."
I was surprised to see that not one affiliate had ever asked her that question before. Not only do you risk losing your commissions, but you risk sharing your subscribers. Any serious affiliate will tell you not to promote a product that has leaks. (Email opt-in boxes)
If you ever come across this problem (you most likely will) then always ask the Vendor, because most of the time they will help.
