This deal is at M&S. It's on the site at £999 but with £200 off at checkout. I know you can get it for £699 less 10% at comet, but you then have to add £265 for the 5 year warranty. Same sort of things on other sites. If you don't want the warranty then not as good a deal.
Looks a like an excellent set and gets excellent reviews on Amazon (where it is £919) and on other review sites.
