The plugin listens for events triggered by the various social networks. When it detects that a user has shared or liked your product, the discount is instantly applied, and a customizable thanks title and message is shown; all without the page refreshing.
By default, the sharing buttons will be shown automatically after the content on all your products. By using the included shortcode you can fine tune the placement on a per product basis, or even include the sharing buttons on posts and/or pages.
