When I go to the in-game or a website, it shows me the original pricing, which is more than 2x more expensive than regional.

Hiya, you should be able to upgrade your Supporter Pack purchases via the same method of purchase (i.e. Steam) however, if you have any issues with this you are welcome to contact [email protected] and we can look into this for you.
