This deal is as old as time itself, comes round everytime there is a new Bond film out.
Play.com are offering buy one Bond film and get another free, checked on a few of the other usual sites and no mention of the same deal yet. The DVD's are released on the 20th October, so I would imagine the same deal will appear elsewhere at the time.
Good deal if you want to get your pre-order in and ensure you get one free in the process.
*PLEASE NOTE: This is not the Complete Boxset deal posted a couple of days ago. This is a buy one, get one free on all Bond DVDs. This is a genuine deal which will be honoured by Play and it's quite likely that the same deal will appear on Amazon, HMV, Zavvi, etc. So please judge this deal fairly without comparing it to the previous deal and the fact that Play didn't honour orders*
