I'm not really too sure if this has already been posted elsewhere but the ticket365 in shanghai is already accepting booking and payment for the NOv 15/16 concerts. Right now, they only have the 680 and the 480 slots.
you can access their site via
http://www.tickets365.com.cn/tk2005/eng/ticket_detail.jsp According to my very accomodating tour guide in Shanghai... this online ticketing site is credible and she has used it several times.
You can remit your payment or pay it online via credit card.... and you have the option to send your tickets to your overseas addresss.....
anyways.... if you still haven't booked/bought your tickets... you may want to include this options to grab them....
