South Texas Blood & Tissue and the San Antonio Food Bank are teaming up on a way to help blood donors multiply their good deeds during the holiday season.

The “Double Your Impact” initiative will allow blood donors to donate any of their South Texas Blood & Tissue Reward Store points to the San Antonio Food Bank through a link at the online Reward Store. The donation of points can be made anytime before Dec. 31.

The food bank will be able to turn 100 Reward Store points into 25 meals for South Texans.
