We are new in this market so we don’t really know that what type of plugin we have to use. We want to use a Woo Commerce Plugin that available free from Wootheme. So we contact woo commerce that we use this plugin in our website & the team of Woo Commerce replay :
Yes, WooCommerce is a free plugin : [link removed]
You do not need a licence for it.
Please note that you should not include this as part of your theme but you can make a theme that supports WooCommerce.
Including plugins within themes is not good practice and not something Themeforest want from the theme makers.
Other than that you are free to make your theme as you wish
Please provide your suggestion that how can we use this plugin in our theme
