Hello I would like to install an affiliate extension on my cubecart store, so that my customers can promote products and receive a commission on each sale. There are several free extensions on cubecart marketplace, My question is: is it free or are there other costs that I have to pay? Because I tried to install one of these programs [idevdirect], but I could not complete the process because I needed to create an account there and it was costing to open the account $75. If purchasing is a necessity, can you please inform me of the most economical option. My online store is still new (One Month) and I have only made several sales, so I do not have wide investment options. My CubeCart Version: 6.2.9 PHP Version: 7.2.32 I hope you will answer my inquiry Thank you.
