With Alkanyx's Afilliate Program, you can earn 10% of any sale and purchase of all your referred users. To get started, you only need to register an account and then hit the Referrals section in the user menu. On that page you will find your afilliate link that you can insert into your content and make users register while you will get your commission for each of their transactions.
The afilliate link looks something like this: https://alkanyx.com/?ref=12f006d1a605, but you can add the referrer code (
?ref=12f006d1a605) to pretty much any Alkanyx URL and still get a valid referred user.
