I also bought a "HTC Vive Bundle"-key yesterday on eBay for £12, which includes the games "The Gallery: Episode 1" + "Zombie Training Simulator" and the 3D drawing/painting app "Tilt Brush". Nice deal, on Steam these 3 games/apps are priced €20 each.
Today I bought Windlands for €5 at Steam: https://www.roadtovr.com/windlands-currently-75-off-steam-september-4th/
The developers are so nice that they give out additional keys for the Oculus Store: http://keys.psytecgames.com/
