How can I override wp_price woocommerce function in my theme

Hmm how about this?

    function return_custom_price($price, $product) {
    global $post, $blog_id;
    $price = get_post_meta($post->ID, '_regular_price');
    $post_id = $post->ID;
    $price = ($price[0]*2.5);
    return $price;
}
add_filter('woocommerce_get_price', 'return_custom_price', 10, 2);
