CD WOW (some UK retailer?) is selling ME2 for seemingly $36 (at least to Americans):

I had some giftcard money left over from Christmas so I pulled the trigger on it, figure I can maybe register it to Steam and then get the free DLC for $14 less than actually buying it through steam. Seems a little shady, but what the heck, right?
