While 7-11, one of the world's most known convenience stores, has been selling new releases of games for quite some time now, they has recently announced that they will be teaming up with Game Trading Technologies, Inc. to sell used games as well. Currently, they only plan to sell used titles for under $20.00 at around half of their 6,000 U.S based stores. Unfortunately, the game list has not yet been released.
This would make the convenience chain one of the first retail businesses to sell video games 24/7, where stores like Best Buy and Gamestop close nightly.
