Freewill Movie Donation

We do not charge for movies at the BIC Center because we want to offer the opportunity to come to see a show to all.  However, we depend on donations to cover the costs of putting on the show (equipment, movie rental, staff).  If you could help with a donation, we would appreciate it.  How much?  Consider how much theater admission is on the mainland and them donate whatever amount you believe is possible.  Thanks
