Nope. Newegg is US only, or next best thing to - when Newegg does ship overseas, the shipping costs make it expensive enough that it's usually worth just buying local anyway.
Novatech, Aria, Ebuyer, Scan and Dabs tend to be the popular UK sites. Amazon too, but less so, they tend to be a bit more expensive. And if you're curious, Umart, PC Case Gear, ScorpTech and MSY are the players here, almost nobody buys from newegg, though I expect Amazon to make a big inroads when they launch here in September.
