It will be the last BYOB (Bring Your Own Box) event of the year - the Holiday BYOB - on Thursday, December 8.
Teachers and nonprofit staff are invited to Sustainable Surplus' warehouse and to bring an empty box and fill it with free office and lab supplies.
"I think they also come for the cookies and hot apple cider," says SSE executive director Sue Prelozni.
PLUS - there will be a visit from Santa Claus!
