SAN ANTONIO - Wednesday marks World Blood Donor Day, and the South Texas Blood & Tissue Center is teaming up with Whataburger and Bill Miller Bar-B-Q to reward donors.

STBTC blood donors who schedule an appointment through Eventbrite and show their confirmation email during their donation will receive a Whataburger or Bill Miller Bar-B-Q $10 gift card.

This offer is reportedly good while supplies last.

Donors are encouraged to take a selfie with a limited-edition bandage being used and share it on social media using the hashtag #GiveInspires.
