Amazon's (AMZN) Kindle Fire tablets will now be distributed by video game chain GameStop (GME). It replaced Wal-Mart (WMT), which said in September it would stop selling the devices because consumers check out products in its stores but buy online at cheaper prices. Target (TGT) ended Kindle sales last May. GameStop shares rose 2.5% to 27.30. Amazon fell 0.04%.
