BCEFA is always collecting one way or another. If you mean after a show when they collect money in the lobby, they do that twice a year for six weeks at a time. It starts from October for the Gypsy of the Year fundraiser and February for the Easter Bonnet fundraiser.
Check the BC/EFA website. They have lots of things for people who have an incredible urge to purchase keyrings, teddy bears, Christmas ornaments and the like. However, it is most definitely a worthy cause.
