Actually, I have something negative to say about them. Nearly two years ago, I ordered a 32" LCD from them. I paid for accelerated shipping. Oops! It took forever to get to me. I would've been better off just doing free shipping. I had a satellite install planned well in advance of the order. I got mad and went to Fry's and bought a rear projection DLP, so that the installer would have something to hook up. I tried to cancel the order, but it was stuck in processing for over a week. A day before it arrived, I got a notice saying that my order had already shipped, and it couldn't be canceled. The whole thing was very shady.
I'm not a fan of buy.com at all. There are a lot of reports of refurb'd items shipped when the customer expected new. In my case, I ordered a refurb'd display. Also, their return policy is horrible. You have seven days from the date shipped *NOT* received.
Unless they had a deal too good to pass up, I would shop elsewhere.
