XCOM : Enemy unknown for PC $22.30 (approx) delivered from The Hut
I was just price checking XCOM at GreenMan Gaming as they have it at 60% off for the next 24 hours and stumbled on the price at The Hut. Its exceptional. GreenMan Gaming at 60% off comes in at $29.98 while The Hut come in at £14.99 delivered which works out to approx $22.30. Not a bad price.
The only difference between the two is that on GreenMan you'll get instant gratification as its a download version, while The Hut need to send you the physical disk so will take 10 days or so.
The game gets some pretty good reviews BTW.
