Just stumbled upon a site called Shareware on sale. I wasn't too sure aobut it initially, but whet ahead as there were two games being given away, one via Indie Gala and one via Humble bundle. You can find details HERE.
apart from other freebies there are decent deals on applications such as IObit Driver Booster, Wise Care 365 Pro, Bit Defender and more. The two free games are Nosferatu: The Wrath of Malachi (usually £2.37) and Teleglitch: Die More Edition (usually £8.99, both Steam keys. Though the Humble bundle one comes with a url that leads you to a page where you connect with your Steam account and the game is then added to your account. :)
