Call Of Duty: Modern Warfare 2 (with Play.com Exclusive Downloadable Media Pack) (COD)
I know this isnt the cheapest but you get the extra downloable media and quidco for another pound!
First add COD 4 MW2 via link.
Add another couple of PC games so the value of basket goes over £50.
Use this voucher code:PLARBS09
This knocks a fiver off COD MW2
Remove the other games from basket
COD MW2 is still £29.99
