Can you advice me some cheaper games to give away?

Hi all,

I am planning to make another puzzle event in the near future. As usual, apart from several big grand prizes, I would like to give away a lot of cheaper games. However, I want those games to be still good games. What I mean here is that for less than 1 euro I can buy some really crappy games nobody will probably play (farm cards at best), but I can also get such great games as The Walking Dead, Goat Simulator, or Outlast. Maybe if you guys saw some good deals recently, you can point me to them to make my event even better. Thanks!

P.S. There is no hidden puzzle in this message.
