Coins bought didn't apply the regional price

Please feel free to contact the team at support@grindinggear.com if you have any issues with any purchases. However, if you are playing the console version of Path of Exile, console purchases are all done through the corresponding console's storefront. For example, for PlayStation Path of Exile purchases, these are all handled directly by Sony via the Sony Store, so you may want to reach out to them if you are having an issue related specifically to purchases made for a PlayStation Path of Exile account.
