begin sell in envato market question

I want to sell my design in envato, ,i have used “Mega Main Menu” in my design, now what should i do? i should buy license for each customer myself or customer should buy license directly or …?

Contact the “Mega Main Menu” Author to use the plugin to Sell it with your theme/template.
He will give you the permission to sell the plugin with your theme/template.
I think The plugin Author may ask you to buy a extend license, To sell it with your theme.

Thanks for your answer, what about free Plugins, if we want to use free plugins in our design do we need to get permission from them, or we could use free plugins?

check the license of plugins if it was free for commercial use you can use it.
