Green Man Gaming offers preorders of downloads of Dark Souls II for Windows bundled with a $12 Green Man Gaming Credit for $49.99. (Don't want the credit? You can instead claim $10 cash back.) Assuming you'll use the credit, that's the lowest price we could find by $12. This game is due for release on May 31.
