By popular request, I've created a page for comments for ticket trades. Only post here if you are willing to trade tickets, or sell for the value you paid for the ticket. Do not post here if you are simply looking for tickets (if someone hasn't posted that they've got the ticket you want for trade or sell, then no one here likely has it) or are trying to sell above face value; I may delete such comments (note that the range of prices for premium tickets is $26 to $83, and regular tickets is $19 to $43).
Double check any ticket before accepting it; I would not accept an under-25 or senior ticket unless you obviously fit that demographic, otherwise you risk not being admitted if TIFF chooses to check your ID on the way in the door.
A transfer through Ticketmaster is probably your safest bet, and then maybe TIFF-printed tickets; personally, I'd avoid accepting PDFs or print-at-home tickets.
Use the information here at your own risk; I do not know anyone who may be posting here, and any arrangements you make are strictly between you and the other person. If you have any issues, there is nothing I, nor the festival, nor Ticketmaster can do for you; you're on your own.
Note if you do post here, you should delete your comment once you have gotten rid of your ticket, so that you don't continue to get inquiries. If you have problems deleting your comment, post another letting me know, and I'll try to remove it when I get a chance.
