When you visit our store from another country, the software should auto-detect your location and offer to show the prices in your native currency (for most common currencies).
If you don't see that, or would like to see how the prices are listed in a currency other than US dollars, there is a selector at the very bottom of the store home page:
This allows you to toggle between different currencies.
If you manage to make a purchase in US dollars even though you are in another country, the amount on your bank statement will reflect the price in your native currency after conversion from USD, so it may be some weird amount.
