Dear Users,

I have a online product / subscription that people can buy/extend monthly, the current way this affiliate system works my affiliates gets commission every month because I setup the setting as this: "Give commissions to the affiliate associated with the user, but if there is none, fall back on any affiliate cookies that may be present".

As I only want to grant the affiliate commission ONLY the first time they buy something and not the rest of the year... I would like to know how to do this? Is there a option such as "give a one-time commission"?
*(only one issue we give away free testing accounts)

A simple workaround for me could be:
I can select "Only use affiliate cookies that are available at the time of order placement" and set the cookie on 2 weeks, but then a user can buy something on our site after 3 weeks and the affiliate don't get any commission. Because we also give users a free week trail.

Help and advice is needed :)
