Hey Nithin, we’ve done this with Hype Discounts: our discount app supports market-specific discounts and lets you set different values for each market. If you need help, just DM me.
Honestly, the simplest way to get this done is with an app from the Shopify App Store. Just search for something like “country discounts” or “market-specific discounts.” These apps are built to let you add extra rules to your promotions, so you can easily say, “this discount only works for customers in France.” It’s a no-code, straightforward fix that works for any Shopify plan.
