Now through September 21, you'll receive an exclusive free PEANUTS mystery bag with one of four special T-shirt designs after you donate blood, platelets, or AB Elite plasma at the American Red Cross.
This promo started on August 29, but I just now found it. I point that out because it says “while supplies last,” so you might want to ask ahead of time to make sure they still have t-shirts remaining if that's your primary goal for donating.
Additionally, you can donate platelets from September 22 – October 5 and get a PEANUTS sweatshirt featuring Snoopy.
