Adding Free Delivery Minimum Order Amount

Hi, @soapking:

Are you sure the meta key is woocommerce_free_shipping_1_settings? Please note that it could be something else, e.g. woocommerce_free_shipping_2_settings, woocommerce_free_shipping_3_settings, etc.

Also, the value coming from 'min_amount' is a raw value, so you should format the output, this way:

/**
 * Add free delivery MOV 
 */
add_action( 'wpo_wcpdf_before_document_notes', 'wpo_wcpdf_free_shipping', 10, 2 );
function wpo_wcpdf_free_shipping ( $document_type, $order ) {
	if ( $document_type == 'invoice' ) {
		$free_shipping_settings = get_option('woocommerce_free_shipping_2_settings');
		$mov = wc_price( $free_shipping_settings['min_amount'] );
		echo "<p>Free shipping minimum order amount: $mov</p>";
  }
}
