In order to display the base price for affiliate products, the following hook must be stored as a snippet. After that, WooCommerce will display the price from the affiliate product directly and also the base price (if any).

function cw_change_product_price_display( $price ) {
		$woo_id = get_the_ID();
		
		$productid = ATKPTools::get_post_setting( $woo_id, ATKP_PLUGIN_PREFIX . '_sourceproductid' );

		if ( $productid != '' && $productid != 0 ) {
			$product_list = atkp_product_collection::load( $productid );
			
			if($product_list != null && $product_list->get_main_product() != null)  {
				$formatter = new atkp_formatter( null, null );
				$product =$product_list->get_main_product();
				
				return $formatter->get_pricetext($product, __( '%s', ATKP_PLUGIN_PREFIX ), __( 'Price not available', ATKP_PLUGIN_PREFIX )). ' '. $formatter->get_basepricetext($product);
				
			}
		}
	
        return $price;
    }
