Hi,
You can see the "geolocation" plugin parameters in our demo website.
demo.hikashop.com/administrator/index.ph...t&extension_id=10053
It uses an API from ipinfodb in order to have the country.
After that, in HikaShop, you can set a currency for a specific country (or state).
Just editing zones to configure it.

By the way, do not send me private message, use the "contact us" form instead.
