Did the thrift shop pay the charities a portion of the proceeds in exchange for the boxes? Sort of. It would have been impossible to track that, but corporate did have some idea what the average box (from a particular source) was worth, and paid them that amount. Or maybe the charity set the price. I don't know. I just know it was different for different sources, and well justified.
