do_action( 'woocommerce_update_coupon' )
When updating this object, to prevent infinite loops, use $wpdb to update data, since wp_update_post spawns more calls to the save_post action.
Description Description
This ensures hooks are fired by either WP itself (admin screen save), or an update purely from CRUD.
