VAT not Included message

[ptsepeli]

Hello,
In my ZenCart all prices are without tax, and the tax rate is selected during checkout.

I want to display a message (on all product pages) informing the customer that the displayed prices do not include tax (eg. VAT not Included).
What's the right way of doing that ?

1. Add it in the Footer ?
2. Add it in the tpl_product_info_display.php etc ?

Any ideas ?

Thanks
