This could be their way of finding a good use for what would otherwise be 'trash';
Instead of dumping them in the landfill, they give them to collectors who will value them for years before passing them on to their heirs.
They are still a loss - but they make customers happy, so they get
some benefit from their expenditure.
Book the 'bad prisms' under "marketing" instead of under "trash".
