The Saving Arizona Blood Drive was held Saturday and it's the largest drive of its kind to help replenish supplies United Blood Services uses to help saves lives this time of year.
Valley resident Gail Hock gave blood for the 62nd time -- a gift she hopes will save a life during the upcoming holidays.
"The only way we get blood is from one human being to another, so there's no substitute," she said.
Hock was among hundreds of donors who rolled up their sleeves for the annual blood drive.
"It's very easy. If you have an extra hour, get out there and just donate," said Gary Burdette. "You do it, it's over with, go on with your life."
The agency serves the needs of 58 hospitals in the greater Phoenix area and every single day, about 700 blood donors are needed.
The goal here is to get 250 people signed up. Free tickets to the Phoenix Symphony were an added incentive, a present for those who can help during a great time of need, says United Blood Services' spokesperson Sue Thew.
"So many people travel with the holiday falling on a Thursday..people take advantage of a long, extended weekend instead of donating blood," she said.
Thanksgiving is the longest extended holiday weekend of the year and United Blood Services says it's the toughest time to get donors -- that's why it's relying on this blood drive so much.
"I have your not so normal O positive, so I get called often. It just makes you feel good to be able to give blood," said Barbara Brown.
The blood bank needs all types, but there's a dire need for O negative. Supplies are down 75 percent because blood has a shelf life of 42 days. These donations should last through the Thanksgiving holiday and hopefully beyond.
To receive a free voucher to the symphony, you can still donate until November 30 at any Valley Blood Services donation center.
