Summer signals the beginning of a busy time for celebrations and summer holidays. The American Red Cross asks donors to make an appointment to give blood or platelets now before calendars start to fill up. Donors of all blood types – especially those giving type O blood and donors giving platelets – are vital to people counting on blood products for critical medical procedures.

The Red Cross has teamed up with Tetris, creators of the iconic, best-selling video game, to celebrate its 40th anniversary and build the blood supply for patients in need. In commemoration, all who come to give now through June 9, will get an exclusive Tetris themed Red Cross T-shirt, while supplies last, plus be automatically entered for a chance to win a trip for two to New York to meet Tetris creator, Alexey Pajitnov. See redcrossblood.org/tetris for details.

Every single donation can help keep the blood supply as stable as possible during a busy time of year when many regular donors may be unable to give. Book a time to give now by visiting RedCrossBlood .org, calling 1-800-RED CROSS or by using the Red Cross Blood Donor App.
