Of course I prefer to pay once and be done that is why I love AppSumo.
I started off loving this. It had the emails needed to send to affiliates so you do not have to come up with all the things but just tweak what they have. I started to fall off when people had to sign in before they apply. I asked if that could be switched they stated "Unfortunately, there's no such option. Information about the affiliate partner is required to process the approval. For example, their email address is required to let them know whether they were approved."
I started to upload things to the partner portal and it did not work after the third item. I asked about it they checked into it and supposedly fixed it. When I started trying to upload again it happened again. Two weeks ago and I still have not heard back from them.
I think I will call it a day and move to something else.
