People who go to WMT may find it more comfortable to shop on-line with a store they know than with AMZN. WMT will do what they have to do and even take a hit to hurt AMZN. Plus the state sales tax issues could hurt AMZN as states get more aggressive with getting their "due." The WMT competition could even be accompanied by unfair practices lawsuits, IMHO. WMT isn't going to roll over and leave AMZN alone. BTW, I don't shop at WMT, but I know that millions do. Let the battle begin. I don't have a position in WMT and have no reason to pump it.
