I don't know. I have no reason to doubt them, but that's less than half the going rate. Seems to good to be true, and the merchant rating thingy (which I've never heard of) doesn't seem to actually load. My guess is that's it's probably a refurb, and while I'm not all that anti-refurb, I'm suspicious of anyone who sells a refurb as new.
At the very least, you should probably purchase it with some kind of fraud protection. Doesn't Visa offer that on pretty much everything now?
