#note for previous coment

For working all price, you need to change file:
administrator/components/com_virtuemart/helpers/currencydisplay.php in
line from 358 (public function createPriceDiv)
public function
createPriceDiv($name,$description,$product_price,$priceOnly=false,$switc
hSequel=false,$quantity =
1.0,$forceNoLabel=false,$extraClassAdded=false){

	// 		vmdebug('createPriceDiv '.$name,$product_price[$name]);
	if(empty($product_price) and $name != 'billTotal' and $name !=
'billTaxAmount') return '';

	//The fallback, when this price is not configured
	if(empty($this->_priceConfig[$name])){
		$this->_priceConfig[$name] = $this->_priceConfig['salesPrice'];
	}

	//This is a fallback because we removed the "salesPriceWithDiscount" ;
	if(is_array($product_price)){
		$price = $product_price[$name] ;
	} else {
		$price = $product_price;
	}

	//This could be easily extended by product specific settings
	if(!empty($this->_priceConfig[$name][0])){
		if(!empty($price) or $name == 'billTotal' or $name ==
'billTaxAmount'){
			$vis = "block";
			$priceFormatted =
$this->priceDisplay($price,0,(float)$quantity,false,$this->_priceConfig[
$name][1],$name );
		} else {
			$priceFormatted = '';
			$vis = "none";
		}
		if($priceOnly){
			return $priceFormatted;
		}
		if($forceNoLabel) {
			return '<div class="Price'.$name.' '.$extraClassAdded.'"
style="display : '.$vis.';" ><span class="Price'.$name.'
'.$extraClassAdded.'" >'.$priceFormatted.'</span></div>';
		}
		$descr = '';
		if($this->_priceConfig[$name][2]) $descr = JText::_($description);
		// 			vmdebug('createPriceDiv $name '.$name.'
'.$product_price[$name]);
		if(!$switchSequel){
			return '<div class="Price'.$name.' '.$extraClassAdded.'"
style="display : '.$vis.';" >'.$descr.'<span class="Price'.$name.'
'.$extraClassAdded.'" >'.$priceFormatted.'</span></div>';
		} else {
			return '<div class="Price'.$name.' '.$extraClassAdded.'"
style="display : '.$vis.';" ><span class="Price'.$name.'
'.$extraClassAdded.'" >'.$priceFormatted.'</span>'.$descr.'</div>';
		}
	}

}
It`s need to work extra classes in output createPriceDiv function and
all prices have to be enabled.
