Overclockers Prices vs Sterling/Dollar exchange rate?

[SilverFish21]

Does anyone know if prices for bundles/full systems/components on OcUK tend to follow the Sterling vs Dollar exchange rate?

If so, how quickly do the currency fluctuations kick in on the website? Hours/days/weeks after major changes in the exchange rate?

So if something is out of stock and Sterling drops in value against the Dollar, it might cost a bit more by the time they get the next shipment? That does make sense... I really hope Sterling doesn't fall much further.
