A tangible (and colorful) way to give.
Printer ink is expensive! Black and color ink for our copier/fax/printer by far takes up the biggest chunk of our office supply budget. We buy house brand refills when we can, save as many files electronically as possible and squeeze every last drop out of cartridges we buy. But some things we can't avoid printing: invoices, letters, correspondence, forms, reports, bills, etc., and the ink keeps dripping away.
