It's no trick the Exchange is treating shoppers with cash for Halloween Published Oct. 12, 2012 By Ashley Sutton Army & Air Force Exchange Service Public Affairs EDWARDS AIR FORCE BASE, Calif. -- The Army & Air Force Exchange Service invites shoppers to see what lurks on the shelves in its latest contest as it gives away two $500 Exchange shopping sprees, ten $100 gift cards for the runners-up and 20 $50 gift cards for third place. The "Halloween Treasure Hunt Sweepstakes" will send Exchange patrons on a "spooktacular" scavenger hunt throughout the store. Using a treasure map featured in the Exchange sales flyer or from the store, shoppers can use the map to hunt for clues within the Exchange. After collecting all five clues, treasure hunters can go to shopmyexchange.com/patriotfamily for official rules and to enter their clues. "This sweepstakes will have you screaming for more," said the Exchange's Senior Enlisted Advisor Chief Master Sgt. Tony Pearson. "In addition to the sweepstakes, the Exchange is stocked with all the Halloween essentials. Don't forget the candy and costumes or it could come back to haunt you." The contest ends at the stroke of midnight on Oct. 31 and no purchase is necessary to enter.
