BuyTopia is offering this Group Buy for tomorrow's 1-day performance of "Legend of Zelda: Symphony of the Goddesses" at the Sony Centre for the Performing Arts
All you have to do is "Buy" the offer on their site for $0 and it will give you access to their promo code, which apparently gives you up to 40% off tickets for tomorrow's show.
Whether you like group buys or not, this is a great deal since the show is tomorrow and the whole transaction is done through TicketMaster. Sounds like a win-win to me.
