Pokémon Cards Spark Chaos, Brawls at Costco, on Video

Chaos at a Los Angeles Costco, where adults were fighting over boxes of Pokémon cards … and the mayhem is all caught on video.

People literally came to blows at a Costco warehouse in Atwater Village, fighting over the right to purchase a set of the collectible trading cards.

Footage shows folks scrapping to get their hands on the merchandise … with one man taking an elbow to the face as he wrestles with another shopper.

Costco employees tried to play peacemaker, but people weren’t having it.

A Costco rep at the Atwater Village location tells TMZ … store personnel responded to an argument between a bunch of customers and broke up the fight Thursday — no one was seriously injured. We’re told police were not called, no arrests were made, and Costco is handling the situation internally.

There’s money at stake here … the Pokémon cards at the center of this are the 151 Blooming Waters Premium Collection, which is going for $120 to $150 online. Costco is selling the cards for under $60, so there’s profit to be made in reselling.

Costco charges a fee for membership, so this is almost like a mini-fight club!!!

The scene at Costco here is reminiscent of last year’s Stanley Cup craze, when people fought for the drinking cups at a Target Starbucks location.
