I bought a camera recently (Panasonic Lumix G1), and I could have got it at least £100 cheaper from a site I found online, but I just didn't know whether to trust them. When I called to ask them if it was UK stock and spec, I was told yes it was, and when I asked how they did it so cheaply, I was told (unofficially) that they don't accept warranty repairs through the site, but you had to go back to the manufacturer. I just thought that sounded a bit iffy, so I bought it locally instead. I'd probably risk a toaster through them, but not a £400 camera.
