Hello Amy, I have observed that as well. From my understanding of Etsy fee rules (I have not reviewed them recently), I had reached the conclusion that their various charges can easily add up (for us and depending on the selling price) to 10%+ for Intl transactions. Etsy imposes us to be paid in Canadian dollars even if buyers pay in their local currency and even if our Bank account accepts foreign currencies, which results on a currency exchange fee being charged by Etsy. Plus, Etsy fees are charged in USD (So it looks like this: listing fee 0.20USD, renewal fee if more than 1 item 0.20USD, payment processing 3% + 0.25 (For Canada shops), transaction fee 3.5%, currency exchange fee 2.5%, and I think I am forgetting one) . As for taxes, they apply only on Canadian sales for us.
