Here's how it works: This one, like any other services, also offers referrals. Generate a code, copy it, and share the link with your friends or even random strangers. That's it! Every sign up is tracked to you, and every purchase they make you get 20% of. Which means if someone buys $15 VPS, you get 3$.
