Hi, just an update for those people that bought this in Jan.
M&S sent me just the Xbox last week but without the Kinect (it was a long estimated delivery date for some reason) so I rang to complain that I hadn't received the Kinect. They said they had made a mistake on the price and that it should be £249.00 and they could not send me the Kinect unless I paid the extra.
I said that it was the first that I knew about it being a mistake and that under the Sale of Goods Act 1979 the item was not as described. I asked them to tell me the complaints procedure but she said she'd speak to her manager. She came back on the phone and said that she would arrange to pick up the Xbox and redeliver an Xbox with Kinect instead. I also asked them to confirm this agreement via email.
Xbox 4GB with Kinect (& Adventures) arrived today - £149 - Perfect!
