Walmart is all about "low prices" and until now they have reigned supreme.  But when a company competes on price, there will always be someone "cheaper" coming up from behind and that's what's happening with advances by Amazon.  Walmart is making it clear they won't give up their position quietly and lately we've noticed a few curious stories in the news.  What does Walmart know about the future?  It's anyone's guess, but you may be surprised to hear about moves the company could be making to fend off competition.
