The American Red Cross has a blood supply shortfall so they’re giving people a reason to donate. The organization says that a shortfall in blood and platelet donations last month is cause for concern. People who donate this month will be able to receive a $10 gift card via email to a store of their choice. They will also be registered to win a backyard theater package. June 14 is World Blood Donor Day and a good reason to roll up your sleeve. To sign up, use the American Red Cross Blood Donor App, visit their website, or call 1-800-RED CROSS (1-800-733-2767).
