Game Changer Charity offers Steam downloads of Hitman: Absolution for Windows and Mac for a minimum donation of $1. That's $19 under the best price we could find for the downloadable version elsewhere, although in February we saw it bundled with two other games for the same price. Donations will go toward pediatric cancer research. Deal ends September 2.

Note: You'll immediately receive an email confirming your donation. A second email, containing your Steam key, should arrive within 24 to 48 hours; although, delivery could be delayed until as late as September 10.
