Firstly, apologies for creating yet another "Help me find COD4 for cheaper than £40" thread, but I have already searched the previous requests and they all seem to have replies giving voucher codes or offers that are now out of date.
So yeah, I was wondering if someone could tell me where I can buy Call Of Duty 4 for the PS3 cheap, as every site I go to is listing it for £40.00. Now I am aware that there is a current "£5 off @ Gameplay" voucher, but I have already used that code once, and even if I create another account under another email address, it still doesn't let me use the code. I also know you can get it around £5 cheaper from eBay/Play.com Traders, but they're all US versions and I wouldn't be able to play my friends online then.
So any ideas? Any help would be much appreciated.
