Country specific pricing

You may start with https://paritybar.com/ by @DannyPostma to see if that's what you need

As @Dinakar and @brunor have pointed out, you can use various plugins to implement country-based pricing.

But if you want to code it out, you can call the IP API and change the currency/pricing accordingly.

If you're doing continent-specific pricing, coding it out is pretty easy. But if you want to do it country-specific, you should use a plugin.

We use Multi-country pricing for one of our Shopify stores.

For Woocommerce there is a similar option Price based on country. We don't use it but it looks promising and regularly updated.

If you're using a different CMS, or a custom platform you can conveniently hand out discount coupons to your customers with ParityBar from @DannyPostma here.
