        'post_type' => 'post',
        'post_status' => 'any',
        'numberposts' => -1
    );

    $lastposts = get_posts( $args );
    foreach( $lastposts as $post ) : setup_postdata($post);

        set_post_type( get_the_ID(), 'product' );
        add_post_meta( get_the_ID(), '_price',         ' >>> PRICE <<< ', true);
        add_post_meta( get_the_ID(), '_regular_price', ' >>> PRICE <<< ', true);
