Hello, dear.

I want to use metabox extention to my wordpress themes.
And I will sell the themes at themeforest.

So, I want to know can I need for services licensing metabox extention or just buy the metabox extention at REDUX site?

If I have to need services licensing metabox extention for selling, how can get the services license and how much the services license cost.
