Remove free word in shipping method label

@andreu, you can put below codes in your theme functions.php:

add_filter( 'woocommerce_variable_free_price_html','remove_free_price_text' );

add_filter( 'woocommerce_free_price_html','remove_free_price_text' );

add_filter( 'woocommerce_variation_free_price_html','remove_free_price_text' );

function remove_free_price_text( $price ) {
  return '';
}

Sorry @terrytsang, but it didn’t work fine ??

Thank you

The code above is for removing the word “Free!” when your product price is 0.
To remove the word (Free) in shipping, use this

add_filter( 'woocommerce_cart_shipping_method_full_label', 'remove_local_pickup_free_label', 10, 2 );
function remove_local_pickup_free_label($full_label, $method){
    $full_label = str_replace("(Free)","",$full_label);
return $full_label;
}

Thanks a million, just what I needed too!
