Maybe, but that doesn’t make much sense either. There is no import taxes that I’m aware of, only VAT and afaik Ebay handles that. I’ve ordered from Ebay in the past with no issues. The only thing the cancellation notice said was “We wanted to let you know that unfortunately this item could not be shipped internationally”.
The seller got a similar notice: “We wanted to let you know that unfortunately this item could not be shipped internationally. As a result, your order can’t be fulfilled. This could be due to import restrictions or eligibility requirements.”
Again, not very useful. Now technically this isn’t the end of the world as it didn’t cost me anything and I have a new part en route. It’s the uncertainty that bugs me. Next time it could be something that I can’t re-order.
