The 2 pack problems are STEAM issues.
1). When you buy a multi-pack, the first one is assigned to your account automatically (you and the developer/publisher have no choice), and the extra copies are given in your inventory as gifts.
2). Once you own a game, Steam prevents buying a multi-pack.

Both of these are STEAM problems that Valve has done nothing about forever.
