Hi,
In the
Virtuemart Configuration >> Price
Make sure to have these settings:
Attachment Pasted_Image_1_24_14__1_24_AM-27.png not found
You should enable only "Baseprice with Tax, but without discounts" (as you see in the screenshot) to get the OLD price (in case of any discount)
Then everything should working as expected. Don't enable any option that you don't need (like "Show price without TAX")
Regards,
Support
