Unserviceable Affiliate Commission: How Fair Is That?

Hello everyone

I got hosting from a reputed host (recommended by many here). I also had an affiliate link that earned a commission of around $ 30. Since their renewal cost was around $ 35, I thought I could use the commission and pay the balance. But to my surprise, the host said, you need to earn $ 100 before you can retire and pay for the hosting.

It may be fine for withdrawing the condition, but why can not you use the amount accumulated internally? I have to move and host somewhere else. This is the first time I have earned my affiliate commission. I think my money is lost.

I just want to know if that's fair.
