If you want pricing to display like this in the module

• Regular Price
• Sales Price
• You Save

I applied same logic John pointed out from category> flexv2.php file

echo $this->currency->createPriceDiv('basePrice','COM_VIRTUEMART_PRODUCT_BASEPRICE',$product->prices);

I went to line 164 in mod_flexible_vm_carousel> tmpl> default.php and editted this line.....
orignal line:
echo "<div class=\"FlexibleCarouselPrice\">". $currency->createPriceDiv('salesPrice','',$product->prices,true) ."</div>";

changed to this:
echo "<div class=\"FlexibleCarouselBasePrice\">". $currency->createPriceDiv('basePrice','',$product->prices,true) ."</div>";

Scroll down to the bottom of the page to see the module in action.... 99cables.com/
