base price without tax

[marvays]

Hi friends.
I have new question

I have shop without VAT. All its OK. But, when I have discount price on products, i cant see my previous base price without tax. This works fine, when i use Vm with VAT = PricebasePriceWithTax. But I need display PricebasePriceWithoutTax
In the virtuemart i see "PricebasePrice" but this price i see always. I see PricebasePrice on the product with and without discount.

Question is: Can I modify category and product detail page for hide "PricebasePrice" and show "PricebasePrice" only on discounted products?

Thx and have nice day.
