There are currently two currencies you can sell tickets with on Skiddle - Pound Sterling (£) and Euro (€).
You select the currency you wish to sell with during the account registration phase: https://promotioncentre.co.uk/register.php
Once you have set up your Skiddle account, the currency cannot be switched, so you’ll have to ensure that you’ve selected the currency you wish to sell with from the start.
If for any reason you have a £ sterling account but have an event coming up in Europe where you need to sell with Euros, you can always set up a second Skiddle account, using a different email address to your first account. All events then listed on this account will sell in Euros.
