Thanks but that doesn’t account for it. I changed currency and paid in GBP. I went back into the website about a half hour ago and it was showing £65. Now it’s gone back to €90 which changes to £81 when you change the currency to GBP. Bizarre. There is no justification for the difference and having bought many items in the shop over the years I have never seen a difference before. Having not received an explanation on the phone I have emailed customer service tonight. For the benefit of anyone who has been ripped off with the £81 charge I’ll update when I receive a response.From what I’ve seen , Irland got charged 90e which is around £81 so yep they charged different for abroad..
there are also bank charges and commissions they will add as well as the Irish tax you mentioned (although I thought that freedom of goods movement was ok in the EU until Brexit)
