tickets help...

i need tickets to see wicked, however the 2 days that i can see the show are already sold out. normally i wouldn't care as i've seen the show already, but i'm going with a friend who seems very interested in the show. i would love for him to see it since he's not really the musical type and i think he could actually really enjoy this show. but anyway, my school does day trips to nyc and they will be on nov 6 and 13. i was going to chose which day to go based on which day i could get tickets, however the matinees (which is what i would have to see) is already sold out. can you think of any other way i could get tickets (besides ebay), without paying abajillion dollars, PLEASE help.
thanks in advance for your help

def. do cancellation line. If you are like 2nd or 3rd on line i have no doubt that you'll get tix.

Look EVERY single day for tickets on ticketmaster. Maybe even a few times a day. They are sure to release some tickets by then.
