First of all this is my first deal, which I thought wasn't bad but there have probably been better ones out there.
In Newcastle (to my knowledge) you got the surround sound and subwoofer free too!
The TV is more expensive everywhere listed here (http://www.google.co.uk/search?sourceid=chrome&ie=UTF-8&q=Samsung+PS51D6900D+Plasma+3D+TV%2C+51%22#q=Samsung+PS51D6900D+Plasma+3D+TV%2C+51%22&hl=en&sa=X&tbs=p_ord:p&tbm=shop&prmd=ivns&ei=4kX2TcT_EYzm-gaL_qzXBg&ved=0CAoQuw0oAQ&bav=on.2,or.r_gc.r_pw.&fp=45db57b78e0b3c5c&biw=1366&bih=643) so as far as i know this isn't a bad deal at all!
Also as far as i'm aware the offer expires on the 30th June (said this in store). I don't know whether the speakers were store specific or if they were even part of the deal, but they weren't listed separately and looked like part of the BR player.
