I haven't sold it yet. However, it's currently listed on Stub Hub. I'm selling it there for cost plus whatever service charges stubhub adds. I'd be happy to sell the ticket to you directly for my cost, assuming I can pull the listing from stubhub.
I purchased a pair of tickets for this concert, but haven't found anyone who's interested in using my extra ticket. I figured that someone on this board must be interested. The seat is in the rear orchestra - Row CC. The ticket is for sale at cost -- $69 plus $8.25 service charge.
If interested, please post a reply here and then send me a private message.
