At the moment, billing is in Canadian dollars.
You can browse the site in certain currencies (USD, GBP, etc) to get an idea of the approximate cost equivalent in your local currency. When you get to checkout, the amount is converted to Canadian dollars at the current exchange rate. You will see the exact CAD $ amount before your payment is finalized.
When you make payment, your currency is converted by your bank or paypal into Canadian dollars. Please check with your bank and/or Paypal to see how they handle currency conversions.
If you would like to pay in your local currency without conversion by paypal or your bank, you can check out our Etsy shop: DreaminDrops.etsy.com - pricing may higher on Etsy due to fees and taxes, but you may decide that route is more convenient for you.
