3 copies giveaway

Yup ;)

Unless that game was in some bundle (HIB for example)...

Have the game you're giving already. :(

If it's not a bundle game, you'll get full contributor value for each of them. The only difference between creating a giveaway for each game separately is it costs more points for us to enter each of them, in comparison to entering only one giveaway with multiple copies. So yeah, there's no penalty in making a giveaway for multiple copies :)
