The Humble Store takes up to 50% off Windows and Mac games as part of its Debut Sale. With items starting at $1.99, that's the second-such sale we've seen from this newly-launched store, and it puts several games at the lowest price we could find, although we saw a straight 50% off more titles yesterday (since expired). Sale ends November 13 at 2 pm ET.

A best bet is a download of Guild Wars 2 for Windows and Mac for $29.99. That's the lowest total price we could find by $12.
