Thank you. I'm hoping so! I'll make the payment and continue with my branding and hopefully it is all ok

Chapaza by Steve Gardener. On the font listing it says $5USD for commercial use but I don't know if that's a one time payment or not.

I've sent a private message to a font author here asking about their licensing fees and have had no response and can see they haven't read the message yet. I've tried finding them through their linked website but the domain name is no longer registered so I'm a bit stuck.
With licensing fees for commercial use, is it typically a one-off payment or is it a subscription type situation?
