Reload an Amazon.com Gift Card before purchase with $100 to get an extra $5 free. Brings the overall price pretty much the same as UK with the possibility of getting import fees back making it even cheaper.
Import item. Exclusive for prime members. You have to take a 30 day prime trial to purchase the item. Import fees likely refunded which could make item as cheap as £145 delivered. I suggest this as all orders i've placed on Amazon.com import fees were subsequently refunded. These orderes Included a Shield Console and a Shield Portable, both purchased before UK launch.
