theonemorething review for Advanced Shipping Cost Plus

Hi, As indiqued in the page of our app (in "Requirements" section) : "Advanced Shipping Cost Plus app requires Carrier Service feature. Check first that this feature is enabled on your shop." Our app need the "Carrier Service" feature enabled on your store to work. This feature is enabled by Shopify only on these cases : - It is on the Advanced Shopify plan or higher. - Its Shopify plan is paid annually. - It is a development store. It will be the same for all apps that manage "shipping cost". Best regards.
