7-Eleven is promoting a new videogame initiative that is less about hardware and software than it is about going on a virtual shopping spree. 7-Eleven and Nexon America have teamed up to make the chain be the first convenience retailer in the United States to sell these cards. Gamers can use the prepaid cards to redeem virtual in-game items and accessories within the MapleStory, Audition and upcoming KartRider games produced by Nexon. The prepaid game cards available in 7-Eleven stores are sold in $10 and $25 denominations.
