Ubisoft has a special sale on the digital version of the Heroes of Might and Magic V pack (which includes the basic game and expansions) for $15. That's $5 less than on Steam (Heroes V wasn't part of their Summer sale). However, the offer is open to residents of the United States only.

The Nintendo DS game Might and Magic: Clash of Heroes is also on sale at $15, which is roughly half the regular price. The HD version (for PS3 and Xbox 360) is coming later this Summer.
