Shopping for a Kindle? You won't be getting one at Walmart. The chain has decided to stop carrying Kindles, and will only be selling off its "existing inventory and purchase commitments" from here on out, it said in a memo to store managers yesterday. Amazon has Walmart handily beat in online sales, and Kindle tablet users can shop Amazon.com on their devices—putting it deeper into competition with Walmart and other retailers, Reuters notes. Walmart sells other tablets and e-readers, including the Apple iPad and Barnes & Noble's Nook. Target, too, no longer sells Kindles.
