Went into Argos to see if they have any good deals on XBOX bundle but came across this on their Clearance section instead. It's not on their website nor you would be able to find it at their machine but if you give them catelogue number 928/4999 at till, they should be able to find it.
It has Halo Reach design on packaging but has nothing advantageous for Halo Reach game as far as I know.
It's this one: http://www.play.com/Games/Xbox360/4-/16178901/Xbox-Live-12-Month-Gold-Membership-2-Bonus-Months-Halo-Reach-Design/Product.html
I hope you guys think it's a good deal too!
Found this at Oxford city centre.
The Ring and Reserve service on 0845 640 1010 does regonise the number 928/4999 and allows you to check stock but advises it is from an old catalogue.
