Currency on board from an Italian Port

How are you charged for purchases on board the ship when sailing from an Italian port. I know that a 22% VAT tax is charged ? is this in Euros or in USA$ Thank you and happy cruising .

As far as I know, only Spain has been charging VAT on purchases on board, if sailing from Spain, and there is a way around that- has to do with where the ship stops...needing to stop outside the EU.

The currency on board will depend on the cruise line. US/American oriented ships will use USD.

They have taken Euros and dollars from me.
