GameStop Corp. today announced that it has launched a store on its Facebook page.

The multichannel retailer, No. 115 on Internet Retailer’s Top 500 Guide, says consumers can not only shop for digital games through Facebook, but also pre-order titles for pick-up from the chain’s 6,670 stores. The Facebook store also enables customers to earn points on purchases via GameStop’s PowerUp Rewards program, and to redeem those points toward purchase.

GameStop, which has about 1.9 million Facebook fans, developed the store with technology from Adgregate Markets, including the Facebook application ShopFans. Orders processed through the Facebook storefront are protected by processing technology from web security vendor McAfee. The GameStop Facebook store also features product videos and reviews, as well as a store locator tool.

“Social commerce on Facebook is a natural complement to our trusted store and online networks,” says Kelly Mulroney, vice president of e-commerce at GameStop. “We have millions of customers already engaging with us on Facebook, and ShopFans gives those loyal fans more reasons than ever to shop GameStop across multiple channels.”

Shawn Freeman, senior vice president, general manager of digital business at GameStop, will speak at the Internet Retailer Conference and Exhibition 2011 in a session entitled “The m-commerce maze: How to sort out the technology that will power the next shopping revolution.“
