If they ever changed the policy I could fly from Ireland to the US buy the I7/512GD SSD have a coffee and fly home all for the same price of buying it in Ireland. Currently a €584 difference in the price between the US and Ireland. Any tax minded people know if this is caused by Irish VAT or pricing structure? Its even €60 cheaper in the UK, €50 cheaper in Germany.
