Seems like what is good for the goose, should be good for the gander. The next time you notice a price on your receipt that doesn't match the shelf sticker, you should be able to exit the store and then call the police to complain about being cheated. All retail stores make those mistakes, some more than others, and when you call it to their attention they act like it's no big deal.

KMart will get their reward. I'm sure that there are a lot of people who will stop shopping there because of this. They could have handled this situation more diplomatically.
