Hello,
As Nicolas told you :
To know exactly which view file to edit and how to edit it, you can read this:
www.hikashop.com/support/documentation/1...-display.html#layout
We do not have the required information to know the context (and the configuration) so we cannot know the view you need to edit.
As Nicolas told you :
This indicates that you have the "show taxed prices" setting activated in your HikaShop configuration.
So the prices of the products and the sub total prices include the tax.
So you can change that setting to get the price without taxes ; then you can use the previous code but in the product page (as Nicolas suggested in a way by giving you the value to force the display of taxed prices).
Regards,
