Hi there,
Indeed, I took a look and it's something we can improve.
So here is the fix, just edit the file view.html.php in components/com_hikashop/views/product/ and change this line:
$currencyClass->getPrices($elements,$cids,$currency_id,$main_currency,$zone_id,$discount_before_tax);
to this:
$defaultParams = $config->get('default_params');
$detault_display_type=@$defaultParams['price_display_type'];
$currencyClass->getListingPrices($elements,$zone_id,$currency_id,$detault_display_type);
It should work
