Negotiation is created to skip the bid option where you can spend more then 20 tokens for one player !
The game take from 7 to 10 tokens to open a negotiation and after that charge 2 more to rise it !
The problem of negotiation is that you make an offer but if the owner don`t log in 24 h to accept it is worthless ...
I bid until now like 4 or 5 players on negotiation and i din`t get any success because the owner din`t log (or he don`t want to get 2~3 tokens extra and over price of player )
