	$categories = array();
    foreach( $order->get_items() as $item_id => $item ) {
    	$pid = $item['product_id'];
        $pcats = wp_get_post_terms( $pid, 'product_cat' );
        foreach( $pcats as $key => $value ){
        	if(!in_array($value->name,$categories)){
            	array_push($categories,$value->name);
            }
        }
    }
    echo '<b>This product belongs to following categories: </b>'.implode(' , ',$categories);
