PS3 - £49.99
XBox 360 - £49.99
PC - £34.99
I know this isn't the cheapest price it has been, but for those who forgot to pre-order the limited edition it's in stock here and only here.
These are selling on ebay for between £64.99-74.99 as they are really rare, so it may be a worthwhile investment.
Please don't vote cold because of the price - that isn't what this deal is about - it's about the fact that it is the only place where it is in stock.
