One lucky blood donor will get more than just free juice and cookies at Trident Health’s blood drive Friday.

All donors will be entered for a chance to win a $1,000 American Express gift card.

Those with O negative blood are encouraged to participate because supplies are low this summer, a press release for the event explained.

The blood drive will run from 9 a.m. to 2 p.m. Friday at Trident Health, 9330 Medical Plaza Dr., North Charleston.

Walk-ins are welcome, but appointments are encouraged.

Call 1-800-733-2767 or visit and enter “tridentmed” as the blood drive sponsor to schedule an appointment to donate.
