The currency you see on the ordering page depends on two factors:
1) If you aren’t logged in, the currency depends on your IP address/physical location. If you are logged in, the currency depends on the country settings for your account.
2) If you’re in the UK, Wordy shows prices in British pounds. If you’re located somewhere in the rest of Europe, Wordy shows prices in euros. If you’re located somewhere in the rest of the world, Wordy shows prices in U.S. dollars.
