Carpat Sport

This is an excellent app. Set up, editing and localization are simple. The Spec Table itself looks great and can be customised somewhat (although we have found it looks great by default), and the functionality is very flexible—there is nothing we have wanted to do that we couldn't do using metafields and variant options. Thanks a lot for your review, we're glad to hear the app perfectly answers your use case. In case you're having any issues or feature suggestions, feel free to reach out to us ;).

Took under 5 minutes to set up and does exactly what we wanted - that is, to tie COD to a separate Shipping Method with a different price.
