Cathy wants to mail 1000 postcards to voters reminding them to vote. It's part of a multi-part strategy to Get Out The Vote. But it costs money! Postcards are $180 and postage will be $670. Can you pitch in to help send them out? $6.70 sends 10 postcards, $13.40 sends 20 postcards, $67 sends 100 postcards, $45 pays for 1/4 of the postcard printing, $90 pays for 1/2 of the postcard printing. Any amount will help!
