I'm on holiday in Scotland at the moment and happened to log on last night and noticed that Witcher 1 & 2 were on an 80% off sale! but I don't remember seeing a news article saying they were on sale. Anyone know why it was on sale?

( the Wifi I have access to is spotty to say the least, it had dropped before I'd managed to buy Witcher 2 though I'm sure I'll get another chance sometime)

It was part of the weekend promo:

"If platforming is not really your thing and you'd much rather refrain from jumping while slaying monsters, solving quests, and getting yourself in all sorts of trouble with the ladies, do check out our franchise promo for The Witcher: Enhanced Edition and The Witcher 2: Assassins of Kings. The award-winning RPG titles, featuring the rugged monster hunter Geralt of Rivia--one of the most enthralling characters of modern gaming, are both available 80% off, and are sure to make the wait for The Witcher 3: Wild Hunt a little bit easier on you."
