Wal-mart is testing e-Play kiosks for automated video game trade-ins. So far they have been placed in 77 stores in New York, Massachusetts, Connecticut and Rhode Island. The machine scans a game, gives a quote and upon acceptance, credit is issued within a couple of days. The price is determined based on a proprietary algorithm that can change daily. If the test is successful, Wally World may eventually have them in most of their outlets and issue store credit.
