Do Premium Themes Come With Plugins

Looking to purchase a premium theme and wanted to see if they come with the necessary plugins or will I have to purchase those also? If I will have to purchase extra plugins how do I find out how many and which ones?

They come with the plugins used to achieve the demo and what you see here.

That said it is a bundled version so you do not get an individual license code for each and updates etc to the plugins are made by the author updating the theme

Thanks you sir.
