If you check it's a real company, registered and all, and they're a UK company, you're legally covered. As long as you have some kind of proof of order, they'd be legally liable for your money either way. Don't necessarily be scared to make an order just because it seems too good to be true. I'm not saying companies like that are often legit, but it is a fact there's double dealings all over the world. Apple would never say it publically, but they sell to their own umbrella companies who then sell to other companies at a greatly reduced price. This way Apple's sales prices are always the same, but they can take agreements from companies for MASSIVE guarantees. This is what stores like Netto and Lidl does from brand name foods. It's why they can offer the same products for nothing. There's a company based in London, that sells one model of iPhone 4, the MC605BA one, VERY cheaply, but they sell quietly, to a handful of loyal customers and they sell in serious bulk. I've personally seen a shipment. The term "scam" is over-exaggerated these days, good business comes from trial and error.
