Clark Street Sports sold out of World Series celebratory caps in two days, and has had to restock several times a day, sending employees out on runs to pick up more gear at a warehouse and even Chicago Midway International Airport.

“It’s like the holiday season,” he said. “It’s so awesome and exciting. There’s such a positive atmosphere that it’s not stressful at all to be this hectic. It’s made it fun.”

Fans have been lining up before Clark Street Sports opens at 10 a.m. to buy jerseys, hats, shot glasses, car stickers and W flags. Javier Baez jerseys have been selling well because of how hot he had been in the playoffs, but the Cubs roster is so deep that most of the players’ jerseys have been flying off the shelves, along with Maddon’s jersey, Savich said.

“It’s interesting because it’s got no logo on it, but people want it because everybody know what it means,” he said. “People are getting emotional. A 77-year-old woman said she had been a Cubs fan for 71 years and can’t believe it. She was in tears.”

Champs Sports at Southlake Mall completely sold out of its first batch of Nike World Series hats within minutes, assistant manager Mercedes McClendon said.

“I’ve seen people reselling them online for $200,” she said.
