I recently bought a handbag on Etsy, and have used it a few times (so can't send it back).
Today, I got a letter from Fedex with a bill for £41.72 customs tax and admin.
I am furious. There was nothing on the Etsy page to suggest that there would be a charge (I paid P&P at the point of purchase) and the bag arrived within a few days of ordering it. It has come from Italy.
I don't suppose there is anything I can do about it, other than pay😡, so I'm posting as a warning to others - check carefully and make enquiries before ordering from abroad.
