If you want, you can do it. But usually people are breaking up every tier's price, based on the number of games the tier has.
For example tier 1: 1$, 3 game (currently, soon 4) so price is 0.33 (0.25) for each game.
Second tier is 4$ - tier 1's price, so 3$ for 5 games, making 0.6$ each game.
With this way of calculation you can sell the other stuff for 3.40 - but this can take time.

I have a leftover key for DRAKENSANG: THE RIVER OF TIME from BM18, and I can split it for $0.60. ($3.00 per 5)

Thanks for the top Adam.

Kuhn I will contact you, thanks.

I wish I had that kind of offer. I guess I'll have to try to win the game in a giveaway. P
