100,000? The population of the city my Wal-Mart is in is around 25,000. The next closest town is 25,000. I'm pretty sure my store doesn't see anywhere near that kind of traffic.

If there were an investigation done that found multiple products ringing up for a few cents more than the price listed on the shelf, I'd say there was merit to it. Otherwise it just seems like a circus act for the media. $100 is hardly a drop in the bucket for Wal-Mart.
