St. Joseph School As part of the TerraCycle program, St. Joseph School collects and gets cash for various brands, including all Mars brands candy wrappers. After Halloween (and anytime), people can send those empty wrappers to school. Collection boxes are the main foyer and cafeteria. The following brands are accepted: M&Ms, Skittles and Twix, Mars and Dove bars. Also, before people dispose of this year's Halloween costumes, they should consider donating it for next year's Green Halloween Used Costume Sale.
