Wal-Mart enters used games business

Major US retailer Wal-Mart has entered the used games market by test-marketing an automated game trade-in kiosk.

The kiosks are currently being tested in 77 Wal-Mart locations in the eastern United States. According to kiosk partner e-Play's website, participants sell games by directly inserting a game disc into the machine, and receive trade-in money directly to their credit or debit card within 2-3 business days.

For now, trade-in prices are determined by e-Play through what the company describes as a proprietary algorithm that can change frequently, according to a Kotaku report.

Wal-Mart is a chain of department stores that is one of the largest game retailers in the US. Last year it was named the top US games retailer by IGN.
