Tickets to "The Glass Menagerie"

I have purchased group tickets (15 tickets) to the 2 p.m., October 31, performance of "The Glass Menagerie" for an incredibly low price of $17.00 each (normal student rate is $39). The play is downtown Vancouver and will be a field trip for the class. I hope everyone can come; let me know asap, so I can make tickets available to the Grade 12 English class if anyone wants to join us.
