I have a friend who has 2 tickets to Arashi's Fuyu Con. Her tickets are for 5-Jan evening con (you can say that it's the all-last fuyu con in tokyo). She wants to exchange these 2 tickets for 2 tickets to 5-Jan noon con and she also wants 6000yen on top of the exchange. If anyone is interested, please email me at firstname.lastname@example.org.
