Donors will also receive an H-E-B gift card and their choice of a thank-you gift from the online donor store.
All donors who give from May 21 to June 30 are also automatically entered into a drawing for a prepaid, two-year lease on a 2020 red Mustang from Jordan Ford.
Blood types O negative and positive urgently needed in San Antonio hospitals
The STBTC estimates that it needs 500 donors a day to keep up with current demand for patients in the area.
Donors are required to make an appointment to avoid overcrowding.
