Thanks for the heads up about BikeIsland. I did confirm that the price on PBK is roughly correct when going to checkout - they will charge 44.59 GBP each for them, not the 51.28 GBP as I thought when looking at the British priced website. The question still remains about how accurate/current the PBK exchange rate is, and the rate that your credit card uses. Even if it's fairly accurate at $71 or so, you're still most likely going to be hit with a roughly 3% transaction fee for the currency exchange.
