I bought HL2:DM for somewhere around 10-5 dollars. It was a while ago. Same with Frozen Synapse. I didn't buy it in a bundle, now stop implying that I'm a liar.
About HL2:DM, then you are a fool.
About Frozen Synapse, I don't care, I just stated it was in a bundle that could've been bought way under the original game's price, and a bunch of people already know about the bundle since every bundle had a topic on the Games section, even now one of the bundles have a topic on the subject (#4).
Eitherway, it's still better to let people choose their games. But I suggest splitting the money to the players based on your budget.
If you have 20 euros/dollars, I think this would work fine:
1st: 10euros/dollars
2nd: 6euros/dollars
3th: 4euros/dollars
