HHhhhmmmmm they email you weekly or something - I got quite cheesed off (in a good way, for you) to see my Seagate Barracuda 80 GB qoing for about £45 (although I had to pay about £60 last November).... so what I'd say id they are responsive and when things are good and sell well - they give best price plus good service....
You see the "kicker is" as they say stateside, I bought that HD from them in the first place at £15 more!
So go for it (when you're ready- always a top tip not to let hardware be shelf ware, like I did, coulda saved meself £15!)
