Walmart announced it would begin taking trade-ins on used video games for store credit, and the move immediately sent the shares of GameStop down in early trading. Walmart though, is late to the market for trade-ins and has a poor game selection for those wanting to trade in old games for new ones. Walmart is also not known for its stellar customer service, which is what this move requires. GameStop has already moved ahead to the future of gaming: extra downloadable content.
