Underpinner Spares review for Upcharge Fees & Product Addons

Thank you for sharing your feedback. While our app doesn’t currently support conditions based specifically on the “Country of origin” attribute, this feature isn’t listed as part of the app’s functionality on our Shopify App Store page. That said, we always try to help merchants find a workaround when a specific condition isn’t available. In this case, you can use product tags - for example, tagging products by their manufacturing country and then creating corresponding fees for those tags. We’d be happy to guide you through this setup so you can achieve the result you’re looking for. Please feel free to reach out to our support team anytime.
