I vote for 'seller should go to the winner server/buyer's server' .As of  reasoning?
 
	 
 
	-If the seller already knowing that 'he should go to other server in case the winner is on different server' means he already ready to take risk , the risk might be 
 
	 
 
	 
 
	° he need to stay on that server for certain time
 
	 
 
	°pay cc price for transfer
 
	 
 
	°give cut price from the agreed deal(like option 2)
 
	 
 
	and if the seller think cross server trade is troublesome ,then why not use server trade then?
 
	 
 
	i think the important things in making money,in trade we call selling,is take the initiative,if u need money take the consequences,if don't want take the consequences just do what you can.
 
	 
 
	Done~
