Alan Wake II on EGS is 20% off at £31.99 in their Holiday Sale, but if you activate the voucher on the front page of the store it knocks another 33% off any time you spend more than £11.99, making it only
£21.43. But there's a second promotion on it for the sale where it comes with a free copy of Alan Wake Remastered (which normally costs £24.99 itself). So both games for £21.43 total.
