My client sells e-courses, e-books, webinars etc. through a simple cart set up. They sell each of these items individually. Now they want to add a membership option where you become a member and get access to all the items in the shopping cart for no charge as long as you remain a member.
Is there any plugin that can sell separate items like a cart and also sell a membership where members get access to all the content as long as they remain members?
