Here is the senario.
3 Players, 1st turn,
Player A Picks a plant and Player B wins the auction. Next Player C picks a plant and wins the auction. Player A must buy a plant this phase, so does he get the same type of benefit as a last place player (ie buy a plant at face value?)
If Player A started the auction and it went to Player B, Player A starts the next auction too. If that 2nd auction went to Player C, then Player A starts the third auction as well. Because he is the only one left, he gets it at face value.
