We get a similar deal here in the UK, one large company offers "ex demo", or "open box" computer parts at a very small discount, but only a 90 day warranty. As Christine BCW says quite correctly, hard drives usually die very early on, but not everything is that way. A couple of pounds off for a lousy warranty, no thanks, if it was half price and depending what it was then it may be different. They must think all buyers are stupid. Perhaps some of them are?
Sorry tmc8080, I'm not being rude to you, but perhaps you may realise that sometimes a bargain isn't. occasionally it is, if your lucky.
