NEW JERSEY - There is a critical need for blood donations, and the American Red Cross is hoping to sweeten the "coffee" pot for donors. The Red Cross says donors of all blood types are urgently needed to help restock the shelves. To encourage more donations, Dunkin Donuts has once again teamed up with the Red Cross to give those who donate blood in the month of August a coupon for a free iced coffee and donut, redeemable at participating Dunkin’ Donuts in the greater Philadelphia and South Jersey region. To learn how you can help by donating blood go to redcross.org. The coupons are available until August 31st or while supplies last.
