Wal Mart Stores Inc. will start offering customers store credit for used video games at its U.S. stores in hopes to boosting its home market business. Customers can trade in their used video games for credit towards any item sold at both Wal Mart and Sam's Club stores. Customers can start trading in used video games on March 26th but they won't be able to buy pre-owned games until later this year. Wal Mart has suffered for four straight quarters of falling same store sales at its locations in the U.S. so hopefully this video game system can help but I don't see video gamers saving Wal Mart.
