As you can see on our pricing pages, all of our membership options are displayed in US Dollars. This is the currency you will be charged in regardless of your location. Whatever financial institution you use to purchase your subscription will be responsible for any currency conversion rates or fees, and we kindly ask that you send any inquiries on this topic their way.
This does mean that, if you are subscribing from anywhere outside of the USA, your recurring payment may appear different each time on your personal billing statement, but it will always remain the same in USD.
