This is an instore only offer.
To get it at this price game are offering the wireless adaptor at £34.99 with ANY other product. Look for a label on the boxes and it is programmed at the tills.So I bought a giftcard put £1 on it and bought the wireless adaptor at the same time and it went through no problem. Got it no problem. If you have giftcards to get for people even better.
This is a glitch in their system as originally the offer was meant to be only if you bought other 360 games or hardware so make sure you get a box with the label saying " with any other item instore ".
