Red Cross Calls for Blood Donations12/09/2019 The need for blood doesn’t pause for the holidays. Between Thanksgiving and Christmas more than 1 million units of blood could be transfused in the United States. That’s why the American Red Cross is urging you to give blood this holiday season. Donors of all blood types, especially type O, are urgently needed. In thanks for being the lifeline patients need, the Red Cross is thanking you with a 5-dollar Amazon Gift Card now through December 18th. Make an appointment now by calling 1-800-RED CROSS.
