I had a few questions related to the configurations and didn't had to wait forever to get the answers.
I'm using wizAffiliates with Hikashop and works well. Even if Hikashop has his own affiliates system I prefer wizAffiliates because of the unlimited (multilevel) affiliates system. Also I can create as many commissions categories as I need and assign affiliates to those categories.
I think it worths paying the price for the features and the support provided.
It is easy to install and set up.
No coding experience needed.
With the module extension added it is even better. You can use inside a module position also, not only in an article.
I had a small problem (my fault) and the support proved very reactive and professional.
If you like the effect then i recommend it to you.
Thanks again for the support.
