Because they're offering 20% off through the weekend with the coupon code "Showers", money conscious fans are able to pre-order The Witcher 2: Assassins of Kings on Direct2Drive for just under $36. I won't be canceling my GOG pre-order over $9, but this is an excellent deal if you want to get into the RPG sequel on day one at a significantly reduced price.
The same coupon code can be used for other titles, which means that a gem like Drakensang: The River of Time can be nabbed for under $16, too.
