Definitely should have gone to specsavers
Slightly off topic but NEVER pay for foreign currency using Paypal as a converter .... The above method mentioned is a must if you can only use Paypal.
If you have the option, use a credit card with no international transaction fees that uses the Mastercard rate (I got the 28 Degrees card solely for the purpose of online international purchases). I've found this gives you the best exchange rate and can save you quite a bit of coin when your total spent over time reaches a couple thousand.
Ditto - got my BankWest Zero Platinum (zero fees too) for that sole purpose too, although I still link it through PayPal to get the buyer protection and so I don't have to hand out my card details to lots of vendors.
