Giddy Giants fans were out in force yesterday trying to scoop up all the NFC Championship merchandise their happy hands could hold.

“We’re huge Giants fans,” said graphic designer Gregory Davidson, 34, of Chelsea, who was at Modell’s in Times Square buying Big Blue gear. “You can’t believe how excited we are.”

Davidson’s biggest purchase was a $60 No. 90 Jason Pierre-Paul jersey that he bought for his 5-year-old daughter, Taylor.

Modell’s manager Marc Sacks said some of his customers stumbled in straight from the bars after his store opened at 5 a.m.

“People are excited about the Super Bowl,” Sacks said. “They’re happy for a rematch [with the Patriots].”

Sacks said sales were up 1,000 percent over a normal day.

Carolyn Elliott, 49, a Midtown speech therapist, could hardly contain her glee as she shopped.

“I’ve been a Giants fan since I moved to New York 23 years ago,” she said. “I’m thrilled to death that we’re playing the Patriots because I hate New England.”
